I had helix testpipes on my stock exhaust for about 6 months.....finally got my injen ses ti exhaust and put my stock Cats back on and still the check engine light. Do i have to some how reset it....or will it go off in time??/ Any info is appreciated.....

 

I believe you will have to reset it. Unplug the negative off the battery for 24 hours. Should do the job.

 

i figured it was something like that ....thanxxxxxxx

 

they have the pump gas pedal/turn the key technique that will probably drive you crazy for an instant restart.

I would just unplug the car over night when you get home to stay. You dont need 24 hours but anything over 3-4hours would be sufficient.

 

dude unplug it for like 5 secs. LOL not a whole day

 

i unplugged the terminal for a good 25 minutes ...and still the light is on......Any suggestions???
