Guys,
I am new to this site (as of today), but I would like to ask you all a question; I live in FL, and my YJ S 2.5L 4 cylinder Jeep ussually works fine. But on the hotter days, after is has run for some time, it starts to fail, as in no ignition (like it's not taking in gas or something).
My first thought was that it was something wrong with the ignition, but I changed EVERYTHING (rotor, distributor cap, cables, coil and plugs). Then I changed the Fuel filter and SURPRISE! I dont think the previous owner ever changed it (the Jeep had 109K miles on it). The thing was FILLED with a mud-like substance. I replaced the filter, and cleaned the injectors and rails (used a cleaning product and then actually took out the injectors and rail and cleaned it out). By the way, the rail and injectors were also dirty as hell... But they are all now clean.
The Jeep actually stopped giving me any problems for about a month, but yesterday it started again. Any ideas on what it could be? The 94 YJ 2.5L does not have an ignition module (you have to change the entire computer, and that's about $500, so I dont want to go in that direction if I dont have to), so changing it is not a possible solution. Could it be that my fuel system is still filled with dirt? If so, what would you guys recomend? Re-cleaning the rail and injectors, and cleaning the fuel tank?
Any ideas welcomed...
