Can anyone help me with this?
For a few years now my car, a 97 dodge neon, has been doing 3 strange things.
- In summer it tends to overheat if the A/C is above level one when driving around town or up small hills.
- the check engine light comes on periodically, and when the key code is checked it says the issue is the oxygen sensor.
- the engine often revs oddly when parked or stopped, like when first turning it on or when stopped at a stoplight. When it is really bad, it bucks when driving sometimes when windy. But it hasn't done that in a while. It usually just revs really high and then sounds like it is about to cut out. It doesn't cut out, but sounds like it.
When I took the car in last for this problem (9/04), they wrote the following: "Check engine light on, idle fluctuates when at idle. Performed scan test. Code P0132, oxygen sensor shorted to voltage and P0134 oxygen sensor stays at center. Ran diagnostic, traced codes to faulty oxygen sensor and replaced with new part. Cleared codes and road tested. Idle is consistent now, idle concern may have been caused by bad oxygen sensor."
And life was good for a few months. Perfect. Lovely. Later that next spring, the check engine light was on again, it was starting to idly a bit oddly again, so I took it in. They checked it (check engine light had turned itself off by then) and told me to make sure the gas cap was closed securely and that it causes a lot of problems. It sounded strange since I always twist the gas cap two or three clicks as habit.
Any help would be greatly appreciated.
