High Idle after Throttle Body Cleaning
Hey all, I have cleaned my throttle body and now my car is reving to about 1700 when I start and stays there. Also, when driving at higher speed it idles at around 2700 when I clutch and stays up there for about 5-10 seconds.
I checked the vacuum hose and it seems snug. I took the filter cover off and put my finger over the mass air flow sensor and it seems to idle normally with it partially covered. I think the engine computer thinks the car is getting more air than it actually is getting.
Also the idle seems to drop when I get to about 40 kph (25 MPH) down to about 2200 or so and again drop back to 1700 when speed lowers to about 20 kph (12 MPH).
The dealer will not do anything unless the check engine light comes on.
Can I do anything or just suck it up?
