Hey guys,

I have a 04 F7EFI I just fouled my second plug of the season (only left plug fouling, not right side). Only have burned two full tanks of gas this season so far.

At WOT, I get a puff of black smoke

AND I have bad low in bog, the sled is spurtering at low RPMs.

I never had any of these problems last year except for the WOT (black smoke) problem.

I had a black magic can on last year, and this year I switched to MBRP.

Need Help
Thanks

Sounds like water in your fuel same thing happened to me this year.
