So yeah the car has been acting funny. Hard starts and low battery charge....and then hesitating a bit, now a lot and now the rpms jump up and down while I accelerate. On the other hand it idles solid, it only acts up while I accelerate. Its almost like its choking. I replaced the battery and spark plugs. Could it be the fuel pump, could it be injectors, could it be fuel filter? Right now its not even drivable. I barely made it back from the gas station at 15 mph, while the car was choking and hesitating. I checked the oil, it seems okay, no other leaks like head leaks. Put the car in neutral and rev it up and it does the same thing, so its not the tranny. Any reminiscent ideas would be greatly appreciated. Thanks guys.
