A little history: I have an 01 cobra with less than 30K miles, it was completely stock when I bought it and I have added Borla exhaust and JLT cold air kit only along with Royal Purple and Iridium Spark Plugs. It was running great when I had to drive it 13 miles to work but now I moved to within 2 miles and I find it runs much better when you can jump on it frequently instead of my 2 mile comute through a school zone so I never get it over 40. The check engine light came on and I took it to my mechanic to diagnos on his computer and he says the light refers to it running too rich. Any suggestions? The car runs much better if you can run it at 120 or race around town once a week but with my lead foot its just a matter of time.
