This seems like a weird problem. I have a 94 Cherokee Sport with 4.0L HO, currently has 248,000 miles and for the most part runs great. If I drive normally and keep my foot "off the gas", everything is fine, but if I accelerate hard pulling out into traffic or off-road, I get a misfire that has the engine shaking side to side and a very distinct exhaust note like a stutter. I have to heavy foot it again, sometimes more than once to get it back to normal, then it runs fine again. Coil, plugs, plug wires, distributor cap and rotor all changed. It seems like it may be the #1 cylinder, when I pull the plug wire to that cylinder there is no change in the way the engine runs, but there is spark. Could getting on the gas cause a problem with fuel delivery through the injectors. I remember reading on a forum a while back that #1 injector has a tendency to clog. Does anyone have any experience with this type of problem and possible solutions? I run Seafoam through it on a fairly regular basis and this seems to help keep it running well. I should mention that the misfire has happens since I got the Jeep and before I started treating the engine with Seaform. Thanks guys. I figure if anyone can help, it's the members of .
