fuel injector lowsignal on one injector, o
1993 saturn twin cam will not run with all injectors hook up. If you pull the one off of # 4 cyl. the car will start. If you hook the injector connection but up the car will shut off.
Car is running lean, because exhaust manifold gets very hot. Have put new 02 sensor and map sensor in. Stumped
Is this a good question?
