1999 Rav4 idle problem! please help
I live in Texas so its warm and when I first start my car and often times anytime I'm at a stop my car idles really ruff. My car has 123,000 miles on it, I have just recently replaced oil, spark plugs and wires, fuel filter, air filter, cleaned the throttle body, and seafoamed my car. This problem has been going on for over a year but it seems to me to getting a little worse. I am not super great with cars but really try taking care of mine.
When I first turn on it idles real low around anywhere to 400-700. It shakes my car real bad. Sometimes it does this weird thing where it vibrates real hard then clicks, and then starts idling real hard again over and over again. This last winter even though not really cold my car did just shut off on me a few times after first pulling out of the driveway. Sometime when I lightly rev up the engine after first turning it on the idle will stay higher around 1000 rpms and then the vibrating goes away but it doesnt always work.
I read that it could be the IAC but would like to find out more about that before I buy the new sensor. I did try cleaning it but it just took an air duster to it and wiped it off with a cloth no real cleaning with like any cleaners or anything.
Please help me out it would really be nice to have a nice idling car again and not feel like I'm going to end up with shaken baby syndrome haha.
