I have 132,000 miles on the car. So the check engine light is on, I got the read out and it says low effincency catalidic I take it to the muffler man he checks it out with a infa-red heat sensor on the catlyst and says its not that. Did he check it right. My car engine hesitates on occasion. Could it be an o2 sensor? AlsoI feel like get as much horse power as I should any suggestions? Should I have the fuel injectors cleaned at a shop? This whole thing basically has to do with the check engine light and it saying low effincency catalst so if its not that could it be an o2 sensor? Any replies would be greatly appriciate thanks
