What in the world would cause a reading of 9.7 on the MAP, when the truck is sitting at idle, warmed up? I was able to check with a scanner. I have no codes coming up, but the truck just idles horribly. The longer it runs, the worse it gets. After long rides, it seems like it almost wants to stall, but hasn't yet.
What's been done?
plugs&wires-ACDelco
cap&rotor
air filter
fuel filter
fuel pump
cleaned MAF
new MAP last year-(threw the code for it)
tranny rebuilt last year
double checked new cap& rotor,air filter,MAF
Still can't figure out what I'm missing.
complete readings from scanner are at old post:
