Truck runs better when MAP is unplugged electrically, but won't drive like that. The truck surges when MAP connected then dies. Any ideas? Have changed out PCV, MAP, reconnected knock sensor, checked injectors. Truck did sit for 3 yrs then was ran with old gas, then new added.
Key is stuck in ignition switch in a 2000 Malibu. How do I get it out?
