Question about Pontiac LeMans
My car has recently developed an issue with a hard start and rough idle at startup for the first 30 seconds, at which time it levels off. From there the car will go from running smoothly to sputtering while going down the road. Everytime it does this the Check Engine Light comes on. As soon as it quits sputtering, the light goes back off. I have changed Coil, Plugs, wires, Fuel injector, fuel filter, and throttle position sensor. There is also occasional "clatter" in the engine upon acceleration (Possibly Detonation?) Any ideas?
I can recommend to RUN scanner/computer for easy diagnostics and fix . God bless you
any components can be faulty

Before changing you pcm try cleaning your egr valve. remove the valve and see if its stuck in the open position if so use a small pick to clean around the spring.

The clamp bolt in the center of the steering column put a small cut in the #5 ignition wire and sent the code to the computer for multiple ignition failures(I forget exactly the terminology that they used and what code; I think it was 0300). The arching must have told the computer to richen up the mixture because you could smell raw fuel. I replaced the wires and ran a can of Seafoam through one of the vacuum lines(brake booster) and all seems well. If I had listened to everything I read at other websites I would have been replacing the Cats and the Ignition Coils-very expensive items. Instead it cost me $50 for a set of wires.
