“My vehicle has been having a hesitation problem for some time now. I have taken it to several mechanics and have not found the problem after spending several thousand dollars. I took it to the local dealer (brown Hyundai) in laredo tx and they point to the catalytic converters (3) and the oxygen sensors. I have had a mechanic remove the catalytic converts and tell me there is nothing wrong with the converters. The vehicle exhaust system reaches over 500 degrees. I have measured it with a heat gun. While I do not know what the proper temperature should be I know over 500 degrees is way to high. …”
