CMC legal coil question

For many of the cars in the series, you can't actually get "OEM" equipment anymore. They haven't made the stuff in a decade or more. When you get it in a box that implies OEM, you pay more but it's the same junk that everyone else is selling...

I feel you, I’ve done extensive research trying to find good parts, ironically enough I have the stock 150,000 mile ignition module on my car because the Motorcraft replacement was junk. That being said I was more referring to aftermarket performance ignition products when it comes to problematic components

Dave/Scott my truck exhibited the very symptoms you describe. Guess what happens when you go WOT? You get WOT fueling. Try new O2 sensors first or better yet, datalog the ones you have and see what you find. Mine threw no codes but would peg full lean. When I'd floor it, the WOT fueling would add enough to make the engine act normal.

I believe at wide-open throttle the eec-iv computer is fueling from the predefined open loop tables, not sure the o2 sensors will help much in this case.
