Hi all

well, i complained a while back that my car seemed to either "misfire" or "bog" in 4th gear (mid range rpm) and in 5th gear as well. I had checked the plugs and wires, that was all ok.

I filled up with 94 octane (instead of the usual 91 stuff) and now that I am on my 2nd tank of 94 octane, the engine bog in 4th is completely gone. The car pulls strong all the way to red line. I was actually surprised, cause today is a really hot and humid/mucky day, and the car is running great.

anyway, the 94 really made a difference (and not just by denting my wallet).

I will switch back to 91 just to see if the bog comes back.
