Re: 1990 c/k 1500 305 tumble, missing, surge ?
my truck was doin the same thing.I tested the Egr valve and it showed to be working right.I then talked to a mechanic and he told me to pull the vacuum hose loose from the Egr valve and plug it up and try it.I plugged it up, and now it runs perfect!!! Ya might wanna try it.
