    Default Warm Start Problem

    Today I replaced my injectors to fix a warm start problem, my old injectors were leaking.

    I still have the problem with the new injectors and am wondering if there are parameters that control fueling when the car is warm, the car also dies when coming to a stop, I have to step on the gas to keep the motor running. The car has a base tune and i'm preparing to take to a speed shop for tuning.

    Any ideas?

    There are numerous parameters that control Idle vs ECT. Without knowing your vehicle, OS, or any thing specific about your set-up..its all a guess.

    I only offer general advice about Idle Tuning..but your problem has come up dozens if not hundreds of times.

    My only advice is to resist taking shortcuts..I.E., well its only warm starts..that does not apply to me. Idle must be done in an exact way to be successful..

    Good luck..
