my car has had a problem missing when at WOT. I get a PFFFF code and Misfire on Cyl 2 on my AP. When the AP is monitoring data and it misfires , the AP reports losing comm. with the ECU.
I was thinking I have a bad plug (30,000mi on current set). However when I switch from my performance maps (custom Tim Bailey protunes) to the COBB economy map it never misfires when WOT.
I am now thinking its the injector on cyl #2. thinking maybe it can keep up with the pulse width of performance maps.
Thoughts? advice? please, and thank you!
