Sounds like when you apply throttle via your accelerator your vehicle is having to negotiate if it needs more air or fuel and then deliver the fuel or air, now if you factor in that we have a cable actuated accelerator for the throttle plate there should be no reason for a lack of air which leaves you fuel have you checked or tried to clean your injectors

Interesting... I do like puzzles sounds like you need to come get a fuel gauge and drive around and make sure you're not losing fuel pressure when you punch it.. Aside from that I can't honestly I think of anything unless you want to get into the electrical side, throttle position sensor MAP sensor pcm itself could be the problem... As a matter of fact it could even be the oxygen sensor... What year Cherokee are you working on if we can hook up a scanner to it that always helps

Had to put an airtex in it from advance, the whole assembly. I just replaced the fuel filter and pressure regulator too. I cab track down a gauge and make a run around the neighborhood this weekend to verify I'm losing pressure. I'll probably fork out the money for a Carter since I've heard good things about them.

Anyone heard anything about MTS fuel pumps? Might try one of those out if that ends up being the issue. I also think I'm putting a new distributor in Friday to rule out Cam Position Sensor.

The Beauty of pre-od2 diag. Check fuel, and check your cam, crank sensors and your MAF. It should be easy to find the resistance tolerances for the cam and crank sensors online and the maf. Good luck!

My reason for swapping the distributor in is that you have to remove it anyways to replace the sensor and it's only a little more expensive than the sensor itself. Jon, does Bosch sell the whole assembly or just the pump? All I can ever find is the pump. I guess I'll dig the old assembly out of the trash before I put the can out to the curb unless I could swap the bosch pump into the new assembly.

If bros got the dough, I don't see why not replace the whole kit and kabootle. I mean, distributors don't really wear, but if he wants to replace the whole thing I don't see why not. He is right about the price though, I think it's literally like ten bucks difference

Mine has the style like the renix where it's around the shaft itself. It's a pain in the *** because I wish it had the one where you could pop the cap off but I checked it when I put the motor in. Should've just replaced then but it ran fine. I might check the coil for cracks because I was hitting creeks pretty hard and I think I soaked the engine bay pretty good. Got it at work today but have been to busy to actually test anything yet. :/
