Car: 2000 Nissan Altima GXE - 4 cylinder automatic
I had a tune-up and my oil gasket replaced recently because it was leaking oil, not running smooth at idle and check engine light is on. Engine doesn't miss when accelerating. So I get car back and oil leak stopped but engine is still not running smooth at idle and check engine light keeps coming back. So I took it in again, this time they replaced the new wires they installed the week before. Engine still idles rough and exhaust sort of putts or puffs at idle only. So I take it back in again and they clean the throttle body. So.
Before I took it in the engine didn't idle rough anything above around 1000 RPM. Just below say 800-900 RPM it started idle rough. That's when they tell me they will clean the throttle body. When I get it back now, the car never idles below 1000-1100 RPM. I put in 1st gear and engine actually accelerates to around 1400 RPM before going back to 1000 RPM. It keeps doing this with me not even touching the gas. Does a similar thing in 2nd gear. Accelerates by itself in gear (drive).
What did they do and what do I tell them to undo when I take it back? I don't want to sound like a rookie.
have the same problem?
