1998 Chevy Malibu

1998 Chevy Malibu 4 cyl Front Wheel Drive Automatic

My daughter has a 1998 Malibu, 2.4L. The problem is that you can be driving along and the motor will just shut off. This happens (so far) when the motor is hot. There isn't any theft device on this because it is a no power windows, locks, or remote starting devices at all on this car. I found that it will start by pressing the throttle all the way to the floor and cranking the motor over. It doesn't take long for it to start but starts in a very rich blubbering condition. Sometime when you rev it up up it will clean up and run fine for a while but it's getting worse now. When you are driving even in a almost "limp home mode", and you press down on the accelerator it will really response to the call for the acceleration. I was told that it was the fuel pump but due to the rich condition and the acceleration ability I personally don't believe thats the problem. I believe it's in the ignition area. I know this car is plug sensative and have replaced the plugs not a long time ago. I have to replace the fuel pump and sending unit (as you probably know already they come together) anyway because when the gas gauge comes down off of the full mark when full of fuel, it will only come down half way then it will go back to the full position. So anyway that issue will be taken care of. Talk about scewy! Anyway do you have any ideas?
