Engine Performance problem
1999 Oldsmobile Achieva 4 cyl Two Wheel Drive Automatic 104211 miles
At times when the car is idle at a stop light it will have a slight hesitation/skip/jerk and the RPM will drop very slightly then immediatly go back to normal. While it is parked in the driveway if I rev the RPMs pass 2K and let off the gas and let the RPMs drop back to normal it will drop below 500 RPMs and act like it will stall and the interior lights will go dim for a second before it jumps to its normal operating RPM. On the highway if I am driving above 45 mph and at around 2K RPMs and let off the gas then press the gas slightly to accelerate it will hesitate and buck, the RPMs again drop slightly but will grab and go after a few seconds of this hesitation. Normal street driving the car will hesitate/skip/buck/jerk when I apply light gas pressure to accelerate (it will hesitate, jerk etc. Around 2k RPM) Driving uphill at 2k RPM it does the same thing only the hesitation, jerking is much more noticable. I've taken the car to multiple repair shops and have had the spark plugs replaced, boot to ignition coil replaced, coils replaced. I also had injector cleaner and fuel system cleaner, nothing has worked and repair shops have no clue what the problem is. Please help, I am a single mom and this is my only car I have, I drive my 6 mo baby in this car and I am worried that I will get stuck. I have no money to buy a new car and took out a loan to fix this one however no one can fix this problem. Any help is appreciated. Thank you!
