New to fieros and some general questions! (Page 1/2)

Good afternoon, all -
Just picked up my first Fiero after wanting one for the last million years... I remember in my single digits seeing one and loving it.
With that being said, i drove 3.5 hours to this car and 3.5 hours back - just transferred the title today so it's officially mine.

The car is a 1986 SE, iron duke.

Here it is on it's maiden voyage from Bend Oregon to McMinnville.



I got it home and was able to use my air compressor blow out the engine bay, give it a nice vaccuum and a general look around to see what i need to do to get it back on the road.
Most of the stuff i'm able to identify, but there are a few plugs and things i'm unsure of (i'm mainly a mk1 VW guy... had many sciroccos) which are a good bit different.

Thanks in advance!

This is the IAC valve, correct?


The plug next to the dipstick, i'm guessing is the oil pressure switch?
and the one on the coolant neck is the coolant temp switch? (is this one for the computer, or for the dash/both?


i'm not sure what this guy is... it looks like a condenser on my old motorcycle, but i haven't a clue what this is


I'm guessing this is the reverse light switch, or the VSS?


Not sure what this is


Is it OK that this vacuum hose is plugged?


Map Sensor?


It looks like grounds are supposed to be here, but there is nothing - is that fine? noticed it by the headlights and a few other spots.


Does the fiero have a brake light switc on the MC? or is it down below?



What are these mysterious wires going to my back lights?! also, just down below is an open port.... what is that for? does that need a vacuum line?


the plug right next to my shifter cables with the red wires... what is that?

This relay pack?


These here large bundle of wires and plugs... is this the C500 and C203?


This doesn't do a thing, i'm guessing this is to release the hood/trunk?


Windshield seal.... from what i was reading - this is just more or less a "beauty ring" and i can replace this?



some random photos.... car has almost 200k on it, but starts right up, but has some fun clutch issues that i need to work through
seats are shot, carpet is dirty and it needs one hell of a bath....

Welcome to the madness.

#1. IAC
#2. The sensor with 2 green wires (one wire is green w/ yellow tracer) is for the temp gage and the HOT warning lamp. The sensor in the coolant neck is the temperature signal to the ECU.
#3. Tach filter (it's a capacitor)
#4. Vehicle Speed Sensor.
#5. Ignition coil plugs, also tachometer feed
#6. The vacuum line is for the EGR - the solenoid for the valve is probably toast.
#7. Correct, it is the MAP sensor
#8. Those are actually cleats for a bra on the front of the car, maybe a Wolf or a LeBra
#9. The brake warning light is on the brake bias valve below the master cylinder
#10. The wires are for the trunk light, the port is vacuum for the Cruise Control vacuum canister.that appears to be missing.
#11. That plug could be for the fuel pump and fuel gage. Is a three wire connector?

Welcome!!!

Your Fiero actually looks like it's pretty complete in the engine bay (just a little dirty), and in pretty decent shape.

Something that's kind of interesting is that your Fiero is a very uncommon model. The 1986 and 1987 SE Fieros basically came with the 86-87 Fiero GT interior, and available options, with the dual exhaust and the aero (notchback) body, but... you could pick a 4cyl or V6 engine. Yours has the 4 cyl, which is the lower horsepower one obviously, but you have all the other options like the interior and such... which is pretty cool!

No and no. With a non-functioning EGR valve, there's a chance that this engine will be running lean and/or "rattling". And grounds are there for a reason.

You've got at least one vacuum leak that I can see, on this tube...

No sir. No EGR solenoid on a duke.

That vacuum port goes to the cruise control solenoid, right? You can see it's missing in the picture, and when I look at the turn stalk in the other picture, he doesn't have cruise. So this port would have just been blocked off, right ... or does it go to something else?

Thanks Patrick, I didn't know that.

Just blocked off with a little rubbery/waxy cap, my Fiero doesn't have cruise control and that's how it is.

#12. Relay with blue and green wires is the A/C clutch, relay with orange and tan/white wires is fuel pump, not sure about the other relay.
#13. The top connector assembly is the C500, below that is the Battery Junction Terminal
#14. Rear deck lid popper.
#15. Yes, it can be replaced, the new part will be wider than the original.
#16. Nice interior, same as the interior in my 86 SE, except I had leather seats.

Hi there!
I'll reply to the windscreen rubber strip:
Your windscreen is glued in, like on most modern cars.
The rubber/plastic strip is just to look nice.
It doesn't seal anything, so just replace it.
Normally, it's just a press fit into the gap between the glass and the windscreen bay.
Cheers, and nice car by the way😉
