Hi,

I was driving my '91 Trans Am to work today when it shut off on me. I was sitting in traffic at a light and when I hit the accelerator, it shut off and the SES light came on. I was able to put it in park and start the car back up. Drove it the rest of the way (about 2 miles) without issues. So when I got to work I did some research on here and figured out how to do the paperclip test. The only error code it's giving is the standard error 12. I replaced the ignition control module and a bad wire about a year and a half ago and that was the last time I had any issues with the engine shutting off while driving.

The engine is a 305 TPI with 700R4 transmission.

Any help is greatly appreciated.

 

that happen to me once in my camaro...... i changed the IAC valve and TPS sensor and it was fine........ how is it that you do the paper clip test?

 

Sounds like your ignition control module again bud, i went through 3 in 6 months.

 

Cleaned the throttle body lately? It gets carboned up and can cause it to choke off at idle. Just spray it out with carb cleaner. I do mine every spring.
