Question about 1990 Oldsmobile Cutlass Supreme Conv
NEW PLUGS, WIRES, ETC. INCLUDING IAC, CRANK SENSOR, AND NEW IGNITION SWITCH. THE CAR OF COURSE DOESN'T RUN AS ROUGH WHEN STARTED NOW THAT THE LAWN MOWER CHAMPION PLUGS HAVE BEEN REPLACED (PREVIOUS OWNER) BUT WANDERING HOW OFTEN THE HEAD GASKETS NEED RESEALING AFTER READING OTHER POSTS. MY HEAD GASKETS SPILL A LITTLE WATER BUT THOUGHT IT WAS NORMAL FOR THESE WITH 14 YEARS ON THE ENGINES.
You have done everything almost. But find a bad resister that is shutting down your quad driver in you computer,You need to ohm them out the reading should be 12.0 ohms to12.4ohms.the top plenium will have to come off. this was a major problem in the late 80's and 90's.
