Is there any way or reason to lube the throttle cable? Just wondering.

I'm assuming you have an automatic. Before taking any measures with your throttle cable, try disconnecting the tv cable from the throttle linkage, if the throttle then feels normal and light, then there is nothing you can do about the stiff throttle. The 3 speed auto has a very stiff spring internally. Don't try driving with it disconnected though! It will damage the transmission. If you have a 4 banger with an auto, there is a linkage pivot, that could get some grease... I'm willing to bet your cable is fine.

You hit the nail on the head. It feels like a stiff spring. I'll do the disconnect test tomorrow.

Thanks,

I tried to lube mine.... but it did not work
I almost crashed the car because the throttle cable got stuck,
I ended up putting the car on neutral and manually move the throttle back.

After I replace the cable I did not have that happen again.

Be carefull

I would recommend - since Fieros are so old anyway - that you simply replace it. A large factor in why the cable wears out is the heat back there, and it pushing and pulling inside the cable. Either the cable shroud has changed shape a bit or/and the wire weaving inside is becoming undone.

The Fiero Store offers stock replacements, and they're actually one of the better products that they sell. They're $50 each, but worth it. They're the exact length and build of the stock cable, and the supplier for them now wraps them in a head shield similar to whats on the shifter cables. It's a well thought out product.

Replacing it on the other hand isn't the most fun. You'd have to remove all of the center console, unhook it from the pedal, and run it up and through the back of the car. What I did was get some colored string to identify where the cable was going as I pulled it. When I got it out the other end, I then was just able to pull it back through from the footwell and it followed the path back down to the pedal. Then it's just reattaching at the pedal and at the throttle linkage. It took about a good hour or so worth of work.

After replacing it the throttle worked silky smooth.

Google "motorcycle cable lubber" these work good on shorter cables and will work on longer cables it you have easy access to both ends of the cable and some patience. You can use motorcycle chain lube, assoil white grease or what ever. I have used PB blaster to clean out the cable first and then lube it.

Use brake cleaner ,hold cable up & squirt brake cleaner directly into the cable,,make a funnel, use a rubber band to hold your funnel to the cable, you want your fluid to flow all the way to the pedal
spray a little brake cleaner in the pedal cable end also..
follow direction in Fiero manual & ajust T.V. cable,,its easy to do
you can jack the car up to assist fluid flow
check wire closely for frayed wire or bend at both ends
a small amount of liquid wrench or PB blaster will be OK
most bike cables the liquid will flow down ward,bike cables are lubed much more frequently than a fiero cable,,, fluid build up at
any bend will eventually collect dirt
try the brake cleaner before you replace

If there is any sort of burr in the cable it needs to be replaced!

Mine was extremely stiff, and would actually make the arch muscle in my foot sore the first couple weeks I owned it (5-speed). One day I finally took a can of white grease, disconnected it from the throttle body and went to work... sprayed a little bit on/down the cable best I could with the included straw, and just kept working the cable back & forth right there by hand. Eventually it started to move a little more freely, and after a week or two of lubing it it starting moving surprisingly smooth, and has ever since (about a year now).
