I drive a 1992 YJ 2.5L 5speed Recently, while driving and while idling the engine has tried to sputter out. The RPM's just seem to drop dramtically. I have been able to power thru these sputtering events by putting it in neutral and pressing the gas pedal down repeatedly.

I thought at first it my have been water in the fuel system to I put in some STP additive to remove water, which I thought was working for about a week until I encountered the problem again.

I have replaced the fuel filter and my pressure at the rail is 29 psi. The plugs, wires, distributor cap, and the computer in the last few months.

Hey Derick


Is the pressurer ate the rails constant? HAve you been able to read it when its sputtering -It sounds like a fuel pump prob to me !


Hopefully someone more familiar with that engine can help-----Bruce
