i instaled a perfomance chip today and the car wouldnt start before removing the stock chip i had a check engine light which needs to be reset and after installing the perfomance chip the check engine light was off. tried to start the car but it wouldnt, i filled it up before installlation with 93 octane. when i put back the stock chip it starts with no hesitation. could the chip be defective or i am not doing something right.
Did you buy it new? If you did, I would call the people you bought it from. If you bought it used, it could be the wrong chip for your car. These chip are specific for certain DME's and year of manufacture.
