ok now i have i/h/e , by the way when they put my exhaust on my check engine light came on wtf is that about?

 

do you still have your catalytic converter on your teggy? they might have taken out the O2 sensor thats suppose to be on the converter but i doubt any shops are that retarded....but then again.....

btw, if the sensor is still on you might wanna check the CEL code coming from the teg

 

Try resetting the ECU , if the CEL is still there after a reset then try and get the malfunction indication code.

It might be intermittent failure or a faulty sensor.

 

yea i'd check all ur o2 censor wires make sure their in correctly and tight they could have been knocked loose when they were putting on the system disconnect your battery for about 3-5 seconds reconnect it and start your car up. this will reset ur ecu. leave your car running for about 2-5 mins. if the lights comes back on u've got a problem and will need to have your car tested for the engine code. complain to the shop who did the work because your check engine shouldnt come one from i/h/e

 

disconnet the negative terminal of your battery to reset your ECU
