Like I stated in my intro post I'm no mechanic, so I'll try to explain everything as best as I can. Please excuse my ignorance.
Check engine light comes and goes on my 2005 Mustang GT. Mostly it stays on. It's always a coil issue. I tried swapping the "bad" coil to a different location, and my reader still says (for this example) coil H circuit malfunction.
Is this more than likely a wiring harness issue, injector problem or a computer issue? The car has been tuned by a local shop and runs fantastic, but this dang light will not stay off, preventing me from passing emissions.
Right now it says I have 6 bad coils. However I have no misfire.
Thoughts?
Thanks in advance!
