Engine Performance problem
1990 Lincoln Continental 6 cyl Two Wheel Drive Automatic 110, 00 miles
We just put in 2 head gaskets and iit runs perfect on our 3.8 eng. Except when it is warmed up well and shut off. It is hard starting like being flooded? Seems like gas milage is bad or computer doesnt work right. Replace tps throttle valve switch, no help. Replaced idle air controller switch, no help.
