plugs are not wet.....im looking into a valve cleaning as it has never been done. i have 50K miles so its about time. I don't think its the cam ledger bearings....at least i really hope not. I did run some logs and it looks like occasionally my car is over boosting between shifts (and not every time), so i need to figured out why.
Again this only happened when my car sees e85. Also ordered new plugs too. |

I have recently replaced all my fuel sensors, and the pumps. the help is about 1.5 years old (10K miles). It almost seems to happen during upshifting. |
