I guess I will buy some carbon cleaner tmrw.
The only thing is I cant work on my car where im it I dont have a garage here and its always rainy or cold.
I think if the idle motor was bad it would just die out all the time, it doesnt die at all it still idles strong but it idles up and down and up and down and then drives itself when its in a gear....
thought it was the MAF but the engine code says different
