Chevy truck issues
Ok, 89 1500 sierra. 305, 5 speed.
starts fine, idles fine. when I drive it cold, it wants to die out, but runs like new when it's warm. new temp sensor on intake, rebuilt distributor, new battery and cables. throws egr code, but it doesnt have cat on exhaust. all vacuum lines look good, but haven't had a chance to check if there are vac lines on tranny.
Can anyone help?
