Engine Performance problem
1998 Oldsmobile Aurora V8 Four Wheel Drive Automatic 117546 miles
I have a 98 oldmobile aurora and I just had a tuneup and oil change done, spark plugs, wires, and oil filter, and when he finished the tuneup I took the car for a drive and as long as I'm on the gas the car drives fine but as soon as I get off the gas pedal my car just cuts off but it starts immediately as soon as I crank it up. Could you please tell me what's going on. My uncle did the tuneup and oil change so I asked him to check the spark plugs and wires to make sure they were all tighten and he did that but my grandfather said he thinks it could be the fuel pump. If you could help me out and explain what's going on so I can fix this car and get it back on the road as soon as possible.
