Miss in engine
 

it feels like i have a miss in the motor when im running in first gear at a low RPM. any idea what this is?

Have you washed your engine recently or did you get water in the engine compartment??? Water down in the spark plug wells can short out the coils. I have been replacing a lot of coil packs at work over the last 3 years, they have a fairly high failure rate. If you have access to a scan tool check the PCM for codes. if you have a code p0301 through p0308 that will tell you which cylinder is misfiring the last digit of the code is the cylinder number. For example a code p0301 is for cyl 1 and a p0304 would be for cyl 4. coils are by far the number 1 cause of misfires on all Modular engines.

Hey Mike, could someone have a degraded coil pack such that the car runs fine on brand new plugs, but starts to miss after a few thousand miles? Then, new plugs seems to fix the problem, then the msss comes back again in a few thousand miles?

Yes that could be the problem. Does the plug look fouled when it starts to miss? If so the coil could be the problem.
