its giving me hell. Man, i feel so stupid because i can not figure this this car out.
When i put the new motor in i switched intakes.to keep the EGR from the impala. I soon came to understand that the last guy that did intake gaskets. stripped like 4 of the Intake bolts and JB wleded threads.So last night i pulled it down to the heads. and put lower and upper intake gaskets. and changed the lower intake. Now the car does not have a high idle. BUT it has a bad miss fire, Hard to start, and just runs like ****. Give me ideas? coils good, ICM good, gaskets are all torqued good.
The first time i went to drive it the VSS was messed up my speedo would jump up the fall back down and the transmission would not shift. i went and bought a new one. now the transmission shifts, But the speedo does not work at all.
