hopefully i get everything hooked up and the deck lid closed up nice and tight befroe we get hit w/ this f'ing hurricane.,... I MEAN WTF, earthquake, now a hurricane !? *facepalm* i hate nature.
harness is done beinng re-wired, now, pretty sure i got everything connected right :P just need to run the coil power/grounds, and i should be GTG for a start test, got the battery on the charger for the night (used it to run a power inverter while we had no power after the hurican, was down to 7v, but kept my alarm clock running lol)
i got a little bit of "cleaning up" to do in the engine bay, but, as for now, it should be driveable as soon as i bleed out the clutch line, and change the rear brakes... (and get exhaust, but it may go for a trip down the road before that happens )
Yay! Now we're about on par with each other again. Did you fabricate an upper motor mount yet? Other then my clutch, the motor mount is the only thing really keeping me from driving my car.

no, i ordered an egr delete plate from WOT, but my stupidity didnt check the pp address, well it went to my old house, so fml... orering another tomorrow, then i was goinng to put the mount on that side of th head somehow im thinking...

its on the tune for the 98 3400, ima do some logs today to see what its doing, so, how did you guys do your throttle cables? :P
On the throttle cable I took a square file and opened up the hole in the 3400 bracket to ~1/2" square. I checked it with a 1/2" drive extension each time I thought it was good. You also need to relocate the loop from passenger to drivers side. It was easier than I thought. It's been working great for a couple weeks now.

the loop? you have a pic of what your referring to? cant seem to picture it
I don't have a picture but the cable section in the engine bay is much loner than the distance between where it pokes through the firewall and the throttle. This excess makes a sideways "U" or what I called the loop where the bottom of the U used to face the passenger side. Because the 2.8L throttle pulls towards the passenger side and the 3400, and I assume 3500, pulls toward the drivers side you need to flip the U around so it's the other way. I hope that made sense. Also I put a 10-32 screw with a nylon insert lock nut through the throttle mechanism because there's no stud for the cable like the 2.8L had. I'll try to get a picture tonight but just a warning, I only have a camera phone.
For now I just have the stock GT cable looped around and slid into the stock 3400 bracket (which looks like it should be filed down to slide the cable all the way in). Then just looped it around the throttle and it sits in there nicely. This of course is only to run the engine and I wouldn't dare drive the car like this. I'll be looking to see if it can reach full throttle and back to zero, then bolting it in like neophile is referring too. Sounds like both of us are going about it the same way.
i know im on a base tune, but im kinda wondering, my idle is up at around 3k... seems a bit excessive even for the 3400 tune :/ any ideas? no DTC's, maf / map look to be good readinngs..
Glad to here it's running again. Are the IACs compatible? How about your air and coolant temp sensors? Check to make sure your throttle isn't wedged open a little (what's the TPS reading). Are the unused vacuum lines all capped off. No leaks in your vacuum lines/accessories. Good luck.

CTS is the stock 3500 sensor, seems to be reading perfect, (and telling me i need to bleed out my coolant system still lol), the IAC's should be compatible, its off a like 97 venture van, looks like the same IAC was used for almost all the 3rd gen 60deg's and most of the 2nd, some of the 1st lol...

This is exactly what I was planning to do with my throttle.
Do you have any hissing noises? For example I thought my hissing was just the intake not hooked up to the filter before the MAF sensor but it was actually the throttle body gasket upside down (must have happened when I changed throttle bodies) leaving a nice vacuum leak. Are you sure the CTS is compatible with the older PCM? I got a custom made one from Milzy Motorsports that was the older designed machined to fit into the stock location in the head. Or are the differences only in the plug?

afaik the difference is just the plug (and the lack of the 3rd "switch" wire) im reading the temp w/ powertuners connected, and it seems to be pretty dead on, no "hissing" that i can tell, but then again, it doesnt have exhaust yet :X
try n get that tonight, my uncle decided to take my door for a ride on the trailer when he left the other day so till i get the new hinges in, opening and closing the door isnt an option and i think when i fell outa the window yesterday i pulled a wire on the aldl out :/
Check to make sure you have +5v going to the TPS on the gray wire. Backprobe the blue wire at the tps. You should have 0.7 volts at the TPS key on engine off. That should increase to 4.6 at WOT. Finally check for the voltage at the ECM connector (it must be plugged in, so backprobe that also with a pin past the seal)

i just fixed it... darths diagram was wrong :/
he has 66 dk blu Throttle Position Sensor signal connect to B of the TPS 33 gry Throttle Position Sensor 5 volt reference connect to C of the throttle position sensor 61 blk Throttle Position Sensor ground connect to A of the Throttle Position Sensor
it *SHOULD* be 66 dk blu Throttle Position Sensor signal connect to C of the TPS 33 gry Throttle Position Sensor 5 volt reference connect to A of the throttle position sensor 61 blk Throttle Position Sensor ground connect to B of the Throttle Position Sensor
i just looked at my circuit diagrams after i ohmed the sensor itself out and seen it was working, changed the wires to correct locations, now it works. ^^pic from 98venture
edit: i just looked at another diagram (01 impala) and it shows them the way darth list... but on the sensor itself it has the labels differently... and so does my pigtail (from a 98 transport van) ill snap pics of the sensor and connector tomorrow to show what im talking about. just googled and found this http://easyautodiagnostics..../tps_test_gm_2.php#1 the pins are "labeled" there as they are on the sensor and pigtail i have.
and as i said before, here are the pics of the damage to my door, i got the hinges, just need to go get a doorskin, skitime is about 1.5hrs from me and said he has one, just need to find the time to go get it.. THE DOOR ISNT BENT, its just not fully closed in the pics, but you can see the nice bend on the hinge in the first pic..

I think the issue is only that Darth is referring to the pins on a 3800 style TPS connector and you are looking at a round TPS connector
The functions of the wires stay the same when you look at the colors. They plug into the PCM the same. But the pins on the round connector are in a different order than the 3800 flat connector
Round TPS connector
3800 TPS connector (Connector on the right)
2.8 TPS connector
The function of the wire - by color - never changes. Only the letter of the pins on the TPS connector itself

no, the wiring diagram for the 01 impala 3400 shows the pins the way he has them... http://dl.dropbox.com/u/177...ed/tps%20wiring2.JPG and asfor the color, im using a replacement pigtail from the dealer, all 3 wires are white, so at the connector itself, i could not tell what color was where
so, today i got a bit of general maintenance done.. torqued down the cradle bolts, installed rodneys clutch line repair kit (another great product from him), *tried* to make my own egr block off plate, we wont get into the details of the outcome of that.... connected the throttle linkage (TY neophile_17, your way worked perfect it seems!)
Seeing there was no 3500 diagram on Darth's site, I assumed (incorrectly) that you used the 3800 diagram for the TPS.
Dang.
nopers, i used the 3400 :P figuring im running the 98 "style" ecu, 3500/3400 is basically the same, 3800 is a different beast, hrm wonder how much of my hair would be missing if i tried to do that? :P
Not sure if that's the best mounting point for the dog bone. That side of the motor is pretty much covered against torque movement because of the two Trans mounts correct? Where as the timing cover side of the motor just has that pivoting engine mount (I used stock, new Rodney Dickman mounts) hence why the dogbone was there in the first place. Using all Poly mounts I was getting some bucking when I pulled back into the driveway on my first test drive (no upper mount) but went away with the clutch in so it shouldn't be too bad to drive around, just don't beat on it (I know, there goes all the fun!) Either way I'm interested in seeing the way you do the upper mount and I'll throw my idea by you when I figure it out.

hrm, from the reasearch ive done, they say the power transfer point is where you should put the torque strut, and plus, my alternator is in the stock location, so putting it there is a nogo, my 2nd idea was to move the coil packs, and put a mount there somehow.
Ya I see what you mean now. I just don't quite understand why the stock front mount has that pivot point. Joseph Upson posted this in my build thread and I think it relates to what we're discussing now.
quote
The block side mount pad is definately not the best place for an anti torque strut and I never felt the stock location was the best idea either. The transmission will be the source so the closer you get to it with the torque mount the better, otherwise you'll have a twisting motion underload, this is why it's still possible to separate the front tranny mount after a while. If the torque strut was connected to the upper tranny bellhousing bolts or the aft end of the cylinder head movement would be much better controlled because the torque strut would be much closer to the center of the opposing force absorbing and pushing against more of the load trying to pull the front tranny mount apart.
With a more powerful motor this will become more significant when using stock mounts.
Putting the dog bone right there where the Trans and Engine mate would be a lot easier then with our alternators being in the way. Would the trunk side fire wall be strong enough to hold though? Should a brace be made extending from the shock tower?

id assume it would be strong enough aslong as the contact point is large enough, and not just like a little 2" square or something.. might do the crossbar or something, have to look into it, wouldnt be a bad idea.

gota set the shift linkage, blead the clutch, and change the brakes, burp out the coolant system, then pissoff the neighbors! :P
