At the moment, not very far out at all. I've never seen it move, but on startup the idle is relatively low, it builds up as the engine warms.
I've seen the adjustment procedure alluded to in Google searches, but the links I've clicked are dead.
My 1987 2.5L had a long crank/ hard start issue over the winter. Only when the weather was cold and the engine itself was cold. I replaced the ISA with a new unit from Rock Auto.
This solved the starting issue, but immediately I was plagued with a high idle. I tried a different new ISA with same results. All vacuum lines look to be in good condition.
Any suggestions?
