PLEASE HELP! Car sputtering when idle, then revs up real fast...
2003 Dodge Neon SE - Automatic
My car has been having this issue for 7mo. I have taken it to two mechanics who still can not figure out the source of the problem.
The car drives normally about 70% of the time. However, some days, I will start the car and it will sputter as it is idling in park and sometimes stall. When it doesn't stall, I will put it in drive and it will drive VERY slow for about 10sec, even when I am pressing ALL the way down on the accelerator, then it will rev up suddenly very fast. After that, it will drive normally at high speeds. Occasionally, when idling at a red light it will start sputtering, shaking, and the lights will flicker on and off (headlights, radio lights, etc). Then it will rev up while I am stepping on the brakes and move forward slightly... it;s kind of scary, especially when there is a car in front of me. Very rarely it will stall instead of revving forward..
The check engine light is on.
The codes are:
I have changed the O2 sensor twice... to no avail. I have added cat cleaner to the gas tank...
My tags are about to expire and I really need help troubleshooting this issue.
Is it electrical? Is it fuel related? Is this a common Neon problem? Is it easy/inexpensive to fix?
ANY help is appreciated... thanks!!!
