Ive been having an issue with the jeep. When on light acceleration in mostly 3rd,4th, and 5th gear the eingine starts to stutter around 2200-2400 rpm. Its not terribly bad but annoying. I have new NGK V power plugs at .035 gap, new wires, disty cap and rotor button. The jeep is a 2001 2.5 5 speed. The check engine light is on also and the code is p1494. Thanks for the help.
