okay, heres the scoop. Its been forever since ive been on pff, but ive been busy with school and trying to get the fi to sc. last time I was back in md, i kept getting a code for my speed sensor. besides that, when the car warms up it shuts off at a stop and backfires. my icm, pickup coil, and all that junk was replaced about2 years ago, spark plugs around 2 years ago, tps maybe 3 months ago,

so I replaced the speed sensor. didnt do squat. I only have a few days while im visiting again to diagnose and fix the car to drive 8 hours!!! Im still getting the speed semsor engine code, and code 32, which ive gotten since day one when I bought it.

Any help appreciated!!! muchos gracias all!!!

Code 32 is your EGR. http://www.fiero.nl/forum/Forum2/HTML/045528.html

Here is a list of all the codes: http://www.fiero.nl/cgi-bin/main.cgi?ECMCodes

hard to say, your egr could be stuck open, or something else. Which codes exactly, are you getting?

The answer to the codes are (and I am posting so anyone else that reads this thread having the same issue gets an answer even if you know what the codes are):

Code 24 Vehicle Speed Sensor:
Code 24 indicates a problem with the VSS (ECM does not receive any speed pulses while driving).

Code 32 EGR Vacuum Control:
Code 32 is by far the most commonly encountered trouble code. The most common cause for this trouble code is a leak in the EGR vacuum lines. This code is often disregarded since a malfunctioning EGR system seldomly has any effect on the car's driveability, and only on the engine's emissions. It's also tremendously difficult to diagnose the problem. If your car passes emission tests and is otherwise running ok, it's often not worth the trouble trying to find the problem.

Code 24 could be the speed sensor, but since you already replaced it... probably a short in the wiring somewhere.

Code 32 could be a slew of things. I posted a link with good information above.

All that said, you say " when the car warms up it shuts off at a stop and backfires." I don't think that either of these codes has anything to do with your problem. Keep in mind that the codes will only tell you of electronic failures that the ECM can monitor. It won't help you if it is something like your fuel pump stops working.

Here are some threads that sound like your problem. I did NOT read them, simply searched for "stalls at stop" based on your original post. You will have to determine if they fit your issue or post more details.

Buck and stall at red lights or stop signs
Stall at stops problem, finally tested fuel pressure
Stalling at stop
Engine stalls at lights or stop signs

Nope. I didn't know you have a 4 speed manual in your car.

This has become an intermittent problem where upon the backfire and die, the cel will come on. It will restart fine and run alright afterward. The tps was replaced maybe two months ago. Upon replacing this tps, compared to my old svx, I was unable to set it on the right voltage like the Subaru.

On another car I have been working on I had some what the same symptoms. Check you grounding, don't know which wire that is to the EGR but it could be other grounding since the speed sensor is not functioning properly either. I am not an expert but I am staying at a Hampton tonight.
