Any other symptoms?
Mine was running very strange once it got warmed up and Mattjk and Aaron both said its probably the ECU. Aaron replaced the capacitors in the ECU and it ran perfect ever since.

My symptoms was little to no power which felt like a mad misfire, and TONS of white smoke pouring out the tail pipe.
