Chevrolet Repair: 93 lumina z34, lumina z34, intake manifold


Question
my 93 lumina z34 idles fine when i first start it up and then it starts running rough it will run smoothly for about ten minute and then it cuts off, second I can make it stay running and when im am driving it has no problem running other than it surges a little in the throttle but when I start coming to a stop the idle gets really low and starts bouncing and then the engine stalls.  Please help me out with this it is killing my wallet!!!

Answer
joel ,

You said this is killing you wallet , can you tell me what you have already tried ?

Is the check engine light on ?

These cars have some common problems

1. Iac (idle air control motor)

2. coil or ignition module.

3. vac. leak at the intake manifold

4. egr valve not seating.

5. bad injector

There are more , but you get the idea. Get back with me on what you have done
already and the engine light and we will see if we can work this out for you.
