I have a 91 firebird v6, had an oil leak for years, got it fixed it was the oil filter, then I noticed my oil pressure went through the roof! The guage stayed maxed at 80. Then after changing the spark plugs, my problems started. It wont idle well, or when giving it gas the rpm's slowly go down till it dies. Changed the fuel filter, ign. Module, distributor, rotor, fuel pump relay, plugs and wires. No change. Messing with the fuel pump or injectors will be my last resort, as it was running fine before this. This bothers me-- when turning the key on "Before starting the car" the oil pressure gauge goes all the way to 80 without the car running? Could the oil pump switch cut off have anything to do with my problems? Thanks for any help. Tracey
have the same problem?
