I recently had a problem where the car would run perfect for a good 20-25 minutes, then the idle would start to drop, temps would go up, and the car would eventually shut off.... got that situation all fixed today and now i have a new problem... the car runs fine temps never went over 88, and about 25 minutes after driving it, it starts to idle really hard. It almost sounds like the engine or tranny is shaking, kind of like a squeaky noise its idling so hard. I attatched 2 videos from my cell phone if you cant hear just forget about it lol... but any ideas on what could be causing this problem? I take my car in oct 12th for tuning and want to have the car running perfect for it. thx.
