1992 Jeep xj hesitates to respond?

Posted by admin on Feb 13th

My 92 Cherokee loredo acts as if it has a slow turbo. It’s the 4.0 ho. motor. No additional engine work. (Slow turbo was an analogy.) I step into it and it gives good power on take off, but after about 5-7 seconds kicks me in the but with alot more. Some times while driving or after a short stop with the engine off, the vehicle acts as if it’s got water in the fuel, but if you run it hard for a second it usually clears up.
I am extremely mechanical. I checked out the cam sensor and it is a solid state, (Havn’t found that on any internet sites, I was going to see if it was in adjustment…grr) {And it was on the wrong side of the car} replaced the 02 sensor. oil and air filter replaced yesterday.
I figure, fuel filter would run then stop or not run.
I figure, fuel pump would not give the extraordinary burst of power I get when it kicks in.
Computer???

Ideas guys and gals, Ideas…
The tranny is fine. It downshifts well. Sometimes I get pops through the carb. Butt!!! The timing has no adjustment on this model and the cam sensor seams to be working. The light for the O2 sensor is on but I just replaced it. I understand that I have to go to the dealer for this model. No OBD 1 or 2 hook up. (Or unplug the light is a choice in this matter..lol) It is backwards from a bad fuel pump or filter in that it gains a boost rather than losing power. Starts great every time as well.
I will be checking the choke next. Now…How to pull that off….

It could have to do with the Transmission. It is really kind of hard to say… Maybe not downshifting completely for some reason when you come to a stop and going from say second gear down to first after taking off.
