After market catalytic converter causing engine overheating?


#1

I have a 1995 4-runner that had the original Cat stolen/cut out. My local garage replaced it with an after market model. After replacing, the engine sounded a little off and after driving the car for 5 minutes the engine temp was really hot. I got the car home asap and the next day checked the level of radiator fluid and tried again. Again 5 min then the check engine light went on and I brought it home just as it got very hot again.



what do you think??


#2

Whwn they cut the cat out, did they take the oxygen sensors with it? Was everything replaced?

One other thought is, did they use a proper part number aftermarket replacement or just a jury-rigged generic?
