Well It seems to be running rich and sence Ive had the car (almost 2 months) Ive noticed less performance not to mention it will not run over 5 grand with out freaking out!.. really starting to piss me off..

When I first got it It would run like a raped ape

Its a 91 lx 5.0 and has b303 cam FMS roller Rockers and trick flow springs Underdrive pulleys Moroso cold air box new 65mm TB new EGR plate and new MAS just to mention a few of the bolt ons that could be
causing a problem. the heads are stock but have been polished.
