truck will not run right
i have a 99 chevy silerado half ton with the 4.8L.
it fires and idles jsut fine dont miss a beat but one you get it up to about 2000rpm it starts spittin. i stole the tech 2 GM. computre from work and it dont throw any codes. other than a misfire when we get to that rpm range. me and these new motors dont get alone real well and im not real sure where to even start. |
What is fuel pressure @ 2000 rpm? How many miles on it?

No codes... that is what leads me to believe what others are saying. Otherwise, you could blame it on a few sensors such as a CPS or something.

99 with 4.8 L should be new body style it needs 60psi to run if you aint got it ,it aint gonna run.
