So my car has had a ghost that has been haunting it for years now. It is running a poor air/fuel mixture which tends mostly to show "lean". I know it's lean because last year I installed an Innovate MTX-L wideband O2 sensor.
A couple months ago we thought the problem was solved by replacing the AFM. I have not been driving the car much as I've decided not to make it my daily so I've only put about 300 miles on it since the AFM was replaced. A few days ago I pulled the car out of the garage and noticed the problem was back. The wideband is pegged at full lean and the engine is running rough with some knocking. So "the ghost" is back.
My intention was to move over to Megasquirt but now I'm hesitant. The car was running great, compression numbers good, and timing seemed spot on. I think the problem is unburnt fuel because I smell gas in the exhaust while the wideband shows lean...
My question is can I essentially kill this ghost by moving over to standalone and perhaps wasted spark? And what sensors (including air intake metering)should I be considering? Any recommendations and caveats would be greatly welcomed!
