my 92 z28 will shut off on me while driving, the only thing i can see that could be the problem is the rpms, which will drop below 500 while braking and will kill the car. i lose power steering and will have to pul off the road to put the car into park and to restart the car. i thought it was a heating problem so i replaced the thromstate with a 195 but the tach will still read well above that. any ideas to what my problems are?

 

When it dies, does it start back up right away?

Do you smell gas when it dies?

 

yes i can start it back but i have to stop the car. i dont smell any gas it feels electical

 

If you think it is electrical, I would check the control module under the distributor cap. Also, check your TPS sensor to make sure there isn't any dead spots at the lower voltages.

For non-electrical, it could be a lot of things... clogged fuel filter, bad vacuum leak, failing fuel pump, failing injector(s), etc.

Hope this helps!

Best of luck.

 

why not just throw it in neutral and start it back up? i know its not a fix but pulling off the road while you have no brakes and no power steering is dangerous. i put my car into a pole that way in high school.

 

check your fuel pressure first and see how it is

 

thanks everyone I found one of the bolts to the TPS was stripped out and letting the TPS move around
