I took my car to an import specialist and they charged me $260 to diagnose the car and "fix it"! I took it in thrursday and took it home at 6 today. I drove it around for a couplle of hours and the same problem came up. The check engine light came on and it started idling funny up and down. The code was the idle air controller and or some vacuum leaks. He took off the Iac and said it was clean as a whistle and thats cause I took it off and cleaned it myself. He replaced two hoses and the pcv valve and said it was fixed. Also said he took of the throttle body which I doubt. What the hell should I do? Has anyone else had this problem? He said that there was air bypassing the throttle body somewhere but he didnt know where. I am so pissed off that I had my car there 2 days and $260 later it's still doing the same shit! CAN SOMEONE WHO KNOWS ABOUT THIS SHIT GIVE ME SOME HELP?
