Ok the ongoing banks header problems are continuing!!! They said to check the fuel system. It sounded to them like a pressure problem. The large intake would help not hinder. The jeep was on the highway for a short time and would not pull in 5th gear at all. So i need suggestions on what to check first. Plugs are good/plug wires cap and rotor are new/fuel filter was replaced last year/no leaks in fuel exhaust or vacuum/ what next?
thanks
