as the weather gets warmer the worse the car is running! after 20 min of driving if you accelerate hard it hesitates bad!! if you gradualy give it gas its fine it also stalls out at stop signs too.. any suggestions changed fuelfilter ,plugs, air cleaner..

Check fuel pressure first. Try tapping the MAF see if the engine responds, also. Disconnect the egr see what happens.

fuel pressure with key on engine off is 40 psi
running engime in park is 35 psi
driving stays at 35psi when you accelrate it goes up to 40 but drops back down to 35psi
1992 didnt have the egr valve

Un-plug the maf see what happens.

My car was wanting to stall at intersections and on the highway it would chug unless you accelerated. Replaced the hole rail and injectors from a wreckers and it works fine. Don't know if this would help you or not. Good Luck

What was the solution? As mentioned earlier, this is an outdated thread and should be closed. I will leave that task to the Bonneville Moderators! It would be best if you would PM the OP and ask this question. It appears he is still active on AF, his last activity was 6/17/08. You can post a link to this thread in your PM if you like.
