ok- I have a 1993 Pontiac Grand Am with a 3300 motor. I have been having a problem with it since i got it. I have had the nut. safety switch changed, lock up solenoid, coil pack, ign. module. cooling temp sensor, ign. wires and spark plugs. OK, the problem i am having is......
1) While idiling the enginge surges, the battery power goes down and the lights start to flicker, when i am at a light the ABS light comes on (that just started today)
2) When i start accelerating the car jerks and sounds like it is going to stall then when i get up to a certain speed it starts the jerk and sputters almost like it is missing, the tach meter goes to 0 and it almost sounds like it is going to stall. The only codes that come up is the esc module which we have changed three times and it still does it.
PLEASE CAN ANYONE HELP ME!!!!!!!!
