Engine Mechanical problem
2002 Dodge Neon 4 cyl Front Wheel Drive Automatic 87000 miles
Hi I posted a few days ago about a problem Im having with my 02 neon. I am posting again to update the situation and hopefully get some feedback from the pro's. Ok. Here we go.
1) When starting the car, it turns over and on just fine. It is rough idling, but not erratic. Just kinda feels 'bumpy'.
2)Been this way for about 1-2 months, NO engine light and NO engine trouble codes.
3) At normal highway speeds, (65) it seems smooth, but if I come up behind a slow-poke and drop to 40 or 50, it is rough again trying to get it back up to 65.
4)At stoplights, the roughness gets worse. It vibrates so much so that I hear "du-du-du-du-du" like a thumping noise and if I release the brake it stops doing it, but as soon as I apply the brake it starts again. In neutral it doesnt do that.
5) as I said in the other post, I have changed the motor mounts, both upper and lower, plugs (done by a shade tree mechanic, but were checked by my hubby and he said they looked fine. Could plugs cause this problem?) Air filter, idle air control valve, and plug wires. Again, NO CEL. And it has been going on for 2 months now, it seems like if it were a problem that would engage the CEL it would have been on by now. Am I right? Thank you so much!
have the same problem?
