i have a cam and, i know there is no intake leaks, all new gaskets and still doing it.
the long story is i had this rough idle since the first cam i put in,
this is the second cam and it is still rough at start up cold and hot.
every time i start it barley idles or does not idle at all.
after about 10 seconds it runs good. somtime when i am stopped and in gear the idle searches up and down about a hundred rpm up and down.
could i just run the start up on the injector richer or leaner?
i have all new sensors exept for the coolant temp and map. i cant figure it out. i have no codes.
this is a 98 5.7 vortec suburban 4x4 auto trans, with a lot of performance upgrades.
any help will be appriciated
i can record what its doing if needed
