plus i jammed it full to the top of the filler neck.
i've been pretty good about keeping my foot out of the pedal but it hasn't seemed to help . i got new O2 sensors to install yet hoping that might help , but it's probably just wishful thinking. i'm also going to try a new MAF sensor. can't hurt right ? 118 miles i'll just right it off as preventative maintenance.
i'm just waiting for the weather to break then i plan on tackling the exhaust with a zzp 3 inch DP and a powerlog. hopefully that might gain me an extra mile or two.
thanks for the input SD , it seems like your the only one that responds to us mechanically challenged newbs.
