Hi, I have a 2002 Silverado... I've replaced my fuel pump, fuel filter, spark plugs, wires, and distributor.
Now I'm having multiple misfires and sputtering, but only when the weather and engine are cold. I am having engine hesitations from about 1700 to 2100 rpms. It runs fine at higher rpms.
It idles fine but if the engine is cold and I turn the wheel left or right when the vehicle is in drive at a stop it'll die.
I have seafoamed it trying to clean the injectors but that didn't work either.
Thank you for your time and ideas!
