I have a 1990 GMC K-1500 5.7 manuel. Just recently when I start it for the first time of the day. It starts and it tries to stall, But then it catches itself. This will go on for about a minute. After that it works great. But this morning it started fine. I was told it could be the injectors but no help they are spraying fine. Thanks for your help.

check out your idle air control motor and or map sensor

Why does almost everyone blame the injectors first, my 02 sensor was bad on the left manifold replaced it and it corrected the problem the first response I got from a friend was probably
the injectors, go figure! :screwy:

Thanks for the answers. Everything seems to be fine know. It seems know that the weather is warming up. I haven't had any problems with it idling.

yeah, may be your o2 sensors. two of mine went out and it melted my cats which blocked my exhust and the engine would stall.
