Heres the deal i just installed my utec yesterday. car started up fine and ran great. I let the car warm up and all that good stuff. But the thing is im still getting the same problem i had before i installed the utec i think its a fule problem but im still not sure. I get cat effiency CEL which i got before becuase my cats are gutted. But i didnt know because i didnt have the utec it also threw cylinder 1 + 2 misfire. Need some help with this if anyone has ideas i would appreciate it.
