this is probably not the right place to ask this as alot of ppl on here have 3800 in there cavaliers
my wifes 89 oldsmobile 98 regency brougham 3800 automatic idles around 1500 rpm my question is what could cause this
a bad maf
a bad tps
it has a new air filter, fuel pump, fuel filter plugs wires
what else could cause it to idel so high?
thanks
does any one know what the tps should read on a multimeter
and how would i check to see if the maf is functioning properly
I think about .6 to .7V with throttle closed and around 4.7V wide open.
It should idle high when it's cold. My GTP idles up around that area when you start it in the cold. But as the engine warms up the IAC will let the idle back down til it's back to about 600-700.
at full running temp the engine still idles reletivly high and shakes the car yet there is no "notable movement of the engine"
