When under heavier acceleration the spark dies sending plumes of fuel/smoke out the exhaust and then running on f~all cylinders for up to 20 seconds or so. I've replaced plugs with .9 recently and tried .7, have removed throttle body and cleaned with carby cleaner, cleaned boost solenoid with carby cleaner, replaced coils with eBay green top coils and still have the same issue. It's an 03 BA with front mount, cai, blow off delete, turbo back exhaust and auto. It feels and sounds like the traction control noises if you don't have your burnout button activated lol. Would a faulty o2 sensor have these symptoms? Link to comment https://www.fordxr6turbo.com/forum/topic/95989-loss-of-spark-under-heavy-acceleration/ Share on other sites More sharing options...

Not sure if it was ever tuned prior to me buying it.

Just ordered 6 genuine coils. Link to comment https://www.fordxr6turbo.com/forum/topic/95989-loss-of-spark-under-heavy-acceleration/#findComment-1699723 Share on other sites More sharing options...
