Hey everybody, any help at all is appreciated. I cant seem to find much on this problem, and most people report cars idling high at 1k RPM, nobody seems to have a problem as bad as this one. And even those people dont seem to offer solutions. Here are the symptoms:
While driving and the car heats up, the oil temps hit about 200 which is normal for my car. then all of a sudden it will get really bad rev hang. Like, 20 seconds to drop 1K RPM. That makes it hard to shift and it does it with S mode on and off. When I put it in neutral it will stop falling and sit idling at 2K RPM. If I rev it up, it will sometimes go back down to a normal 600. I am guessing it's because of the constantly high RPM, but my oil is hitting 230 degrees and maintaining that temp.
I went all over the Gen III I have installed a long time ago and found some loose hoses. Tightened them and it all seemed fine yesterday. Now today it is doing it again. Checked the intake and its all still tight. It seemed to have done this after I installed my Stillen exhaust, but when I had it in the air, I couldnt find any exhaust leaks. I installed it about 700 miles ago, and it started acting up at around 500 miles ago. I will put it back up in the air and check the exhaust again when I get home and have a lift, but for now I am out of town and cant do that. Anybody else have ideas?
