I've had multiple problems with my car that I believe are all connected. I think I have it narrowed down to two possibilities so I thought I'd ask you guys and see which one you think it is or if it is something different.
My car has a rough idle, sometimes RPMs surge while sitting there but it also has been known to bounce around. The car has stalled sometimes while coasting down a hill, up to a stop etc. and while sitting with the car in drive (this hasn't happened while in park that I can remember). And sometimes while idling the car seemingly looses power (the engine seems to run softer, A/C blows not as hard etc. but it usually only lasts a few seconds). It also shifts roughly at times. I think it is either the torque convertor or (hopefully) the coil pack. What do you guys think?
I have a 02 GP GT no current mods. For maintenance over the past year I have changed the transmission fluid and filter, air filter, oil and oil filter, fuel filter, spark plugs, spark plug wires, cleaned the MAF sensor, new water pump and serpentine belt
