Hi Dave,

Appreciate the insights.

Here’s the thing, the car was running fine for over a year- still needed fine tuning and cold start work, but it ran and started up each time for about a thousand miles and then suddenly while driving down the freeway at steady speed it lost power and gauge showed 19.9 AFR.

Once I got it restarted, it went from fine to lean intermittently the whole 30 mile drive home.

The next time I started it, it was still 19.9, so I had A chance to try a few things and switching out the EDIS module seemed to do the trick until it didn’t, switching coils seemed to fix it, until it didn’t.

I have pulled injectors and they sprayed fine, I have verified spark and every cylinder sparks.

Early on, I sent my datalog to Jamie Novak from that first failed drive and his thought was it was ignition and I was getting good inputs to the ECU.

So short of replacing everything one by one, I don’t know what else I should do?
