Hey fellas. I think I know the answer but wanted to ask. When I turn my key forward, no check engine light or abs or traction control light appear on the cluster on my mach 1. I have 2 codes pulled from computer. But the normal 420, 430 for x pipe. Do you think my car had been tuned. If so they didn't give me the tuner. Also when spinning the tites the green traction light dont come on. I checked fuse #5 for traction control but fuse was good.
