Hello, My sister in-law has a 2001 Hyundai Elantra with 110,000 miles she just bought used from a dealer. It has no warranty. The problem is that when she accelerates, it seems to bogg down, then instantly picks up. Then repeats. I think it is a fuel issue, but it does not have fuel injection. I thought it could have been the fuel presure regulator, but when I looked it up, it seems that this car does not have one. Any ideas or suggestions?
2001 Elantra WITHOUT fuel injection? You are mistaken. It sounds like a BAD TPS (Throttle Position Sensor). Is there a "Check Engine" light?
If so, retrieve the diagnostic trouble code (DTC) and tell me what it is. Otherwise, you can go to http://www.hmaservice.com/ and register (Vehicle VIN) and you'll have access to technical info about the vehicle (manuals, service bulletins, wiring diagrams, etc.). Please remember to RATE my response..... thanks.
