I just can't win this car. I'm having more problems with the car, I have an 88 2.8 Formula 4t60 automatic that I can't get running right, I just got a scantool from Phonedawgz and went out to start the car, its only been sitting a few days because I've been off work and she would barely idle and just stall out in gear. its pretty much killing me anymore and I don't know what to do, any help or advice or pretty much anything at this is very much appreciated.

Can you give us more information on your car? What has been done to it? Has it sat a long time? What else is not stock besides the transmission?

Were there any codes? What have you checked so far? Cover the basics, check vacuum lines, plugs and wires, cap and rotor, EGR tube for cracks, is the air filter plugged. How new is the fuel in the tank? Is it just an idle issue or does it run poorly when driving too? Will it straighten out if you hold the throttle off idle or higher?

just a code 32 when it was driving for a while, gas is a week old. filter was good but will check, yeah it was running poorly driving too but was drivable when I last had it out. will also check cap and rotor.

What does running poorly mean? Missing? No power? Are there any odd sounds? wandering idle?
Is the problem the same at any speed? In any gear? Does your transmission have a TCC? I don't know anything about that transmission with a Fiero ECM, but something may be not right along those lines....

With a little searching I found this:

Your transmission has a TCC lockup solenoid. Unplug it and see if you have the same problem.

Here is a discussion of the wiring on your transmission...depending on how the swap was done.

beat you to it Gall the tcc has never been hooked, PO let it hit the weatherpack exhaust, I haven't really been having tranny problems but just a slow decline in power from the engine. to recap this somewhat happened before and I took it to a mechanic, the total replace list was new plugs, new injectors, new cap and rotor, new plug wires, new fuel filter, he said he blew out the fuel lines.

forgot to mention that when it started to lose power and everything the air intake seemed to get really noticably loud and there does seem to be a hiss in the engine bay somewhere, kind of sounds like a loud leak. I will check the egr tube and the distributer cap and rotor when the sun comes up.

here were the results from the scantool warmed up and idling, I couldn't drive it at all because it would stall with the scantool plugged in. could someone advise me if any of this is out of the norm as I've no idea what any of it really means.

The only thing that looks funny is the iac is stepped out to 83....fully warm (193f) . It should be only stepping around 30 at warm idle. Where any adjustments attempted to the throttle body?
If you had a vacuum leak, the iac would be at 0 (closed), trying to bring the idle down....but it's not.

If you pulled one and there's a stutter, that bank was contributing. Each bank should be capable of keeping the motor running by itself. If you've pulled a fuse and the motor dies, the one remaining the opposite bank) is the bad one.

Sounds like you have a dead cylinder. Check cap wires plugs. Gap to 40-50 (some go to 55).
If that doesn't clear it up, look into a bad injector.

This is assuming your compression is even across cylinders in each bank.

I'll check the wiring a little later if I can I just got home from work. when I got all the new parts put in the car ran great for a while, I mean I did 0-70 in half a quarter, but then went back to like you said running on one bank, would just a bad ground cause that slow decline or be killing said bank of injectors?

Another idea is if it sat for a week, did a rodent get to a line somewhere? Does the car give off any distinct smells you don't remember?

it doesn't have a cat but still smells pretty bad when its fully warmed up, I don't quite know what it smells like but bugs the crap out of my eyes. I don't think its burning oil at all. and no leaks at all on the garage cement.
