Ls2 idle problem.
I have ls2 swapped my BMW. The problem is car seems to shut down all 4 cylinders and no hrottlebody responding or so. It shuts down the ECU I think. But the other 4 cylinders are still on. It happenes after 30 seconds from start.
when I hold my foot on the pedal about 1200rpm and over car works great. But If i let the pedal go it will just run on 4 pistons after a few seconds. Disconnected the pedal wire to test it does the same thing.
thanks
