    Cold Starts

    I'm having cold start issues since I installed the turbo system to my 01 corolla. The rmp is not steady, but jumps around until the engine get hot. It will stall at times in the morning. One theory is the 380cc fuel injectors installed. We are thinking of replacing them with the stock and use supplementary large injectors to supply enough fuel to the turbo engine. The engine was also rebuilt, but the cold start problem was prior to the rebuilt. Does anyone know what is causing the cold starts problem?

    Well that too, but check to see if the plugs are still good. I had a semi-functional plug that stalled at start but then ran fine at higher speeds. It was really strange indeed.

    if gapping was the problem wouldn't the engine jump around even after its warmed up? i'm thinking more of clogged injectors maybe?
