Hello, I am totally stumped with this problem and need help Badly. My daughters 95' 3.4 5-speed Camaro has had this problem from about 6 months after we bought it and has gotten more frequent. we have owned going on 2 years now. It will start then die imediately for about 20 times, when it does stay running it may run for 1/2 to 2 miles and then start buck jumping, if you give more thottle it will die and when let off it will start buck jumping again. keep in mind that it does not do this every time we go to drive it but is so often now we are afraid of being stranded on side of road. Seem to happen most often in the cool of the morning when the engine is cold.
I have had it to the chevy dealer 2 times and 1 time at a independant garage, they can,t find the problem. I am a half *** mechanic and the cars I work on as a hobby are 2nd gen Camaros and 70-72 Chevelles, I have built a few engines for myself and know my way around under the hood of the older cars.
Here is a run down of the many parts I have bought new to try to fix this problem, some where replaced as preventative maintantance as it has 110 K miles on it.

fuel pump (fun job)
2- fuel filter
IAC motor
Ignition module
computer (used)
checked fuel presure this morning
spark plug wires
altonater
crank position sensor ( both of them)
cam shaft position sensor
cleaned EGR valve

Probobley more but I can't think of them right now.

Please reply if you have any ideas.
thanks Nick

 

What about the injectors??
Is it throwing any dummy lights? If it is, I would try taking it to Autozone.

It is not putting up the check engine light. The last time it was put on a scanner it did not show any fault codes.
Thanks for the reply, Nick
