Anybody on here ever see this crazy kind of thing?
Back story, my car had a huge misfire , more of a "let go" any tune even stock.
Pulled everything out and had a damage tmap ground for some reason. Grounded it locally but same issue.
Since then I have replaced
Harness's
almost every sensor.
lpfp
hpfp
fuel lines and regulator/filters
ecu
the dct box.
The engine, it's now 235 long motor
Something fishy going on.
Doesn't seem like the oscillation is mechanical.
Someone save me.
