Hey everyone. I need help with my Jeep from the gurus here. Its a 1991 2.5L 4 cyl engine with the fuel injection system. It has the injector per cylinder setup on this. I have pretty much replaced all of the sensors on the engine, cleaned it all up inside and even added new main bearings and connecting rod bearings as they where shot when I bought the car. Since doing all the work, the engine has been running smooth and the truck runs alright. But I do notice a lack of power; I know its the 4 cylinder, but I always have to give it good amount of gas to get it going. My biggest headache is that I am getting about 12 to 13 MPG, which I think its insane! I have no leaks on the intake, fuel pump, filter and all those maintenance items are new as well. The only thing that I recall not checking before was the position of the rotor in the distributor when installing a new distributor I got. I used the haynes manual and it stated that when installed, the rotor should be at the six o clock position when you are standing on the side of the engine. The front of the engine is to your right shoulder and the back to your left and you are staring right at the distributor in front of you. In this six oclock installation, I couldnt even get the engine to start. I could feel that the engine would try to start and it would stop the started right away. In a way I feel that it was too advanced. I then began to look around and some other sites are listing that the rotor should be installed at the 3 o clock position, essentially poiting forwards. My question here is. What is the correct rotor position for a 2.5L 1991 Engine with the port fuel injection electronic setup? Any tips here? What other areas could be causing my poor fuel economy? Crank sensor at the rear of the engine? That is pretty much the last sensor I havent touched... Any ideas will be very welcome. At this point i want to drive this daily but with a 12 MPG thats a little absurd...

So for a few weeks my MJ has been randomly stalling. Be driving, and engine will die. Sometimes it'll restart, but usually I have to let it set. MJ would drive awesome, except when it would stall. I thought it was fuel delivery. Cause, after the engine would stop, if I put gas down the TB, it would start. Well, finally it stopped and would not start. After checking the usual, I was kinda stuck. I decided to take a look at the Distributor. I had installed it a few months back, new from AutoZone. As looking inside, I found my problem. The "pulse ring" is pressed on to the shaft. It is NOT supposed to rotate independently of the shaft. On my New Autozone Distributor, that pulse ring is loose. It rotates a few degrees on the shaft, just enough to mess up the timing. I was able to force it on the the shaft to lock it. It's advanced the timing now, I think. I need to put a timing light and see. It will come loose again, I need to find a way to actually lock it. like a tac weld. If it advances the timing, like the CPS mod, I may keep it. Anyone else see this issue before?
