I have a 97 TJ. It 1st started playing up when I was on a road trip with the kids. The CEL came on & it had a very noticeable drop in power with added stutter. The CEL came off after a layover & had no more issues until I was doing 110Km/h on the last leg. The rev's would not come under 1500 for the last 25Km. I flashed the PCM & it worked fine for a week or so, but then the same problem came back.
I purchased a new TPS & had a full tip to toe service, (I was working 9 shifts a week so had no time to do any work myself) and the problem seemed to clear up.
I am now on a holiday with the kids & the same problem has come back, minus the high revs. This happens at both low/high revs, 1st gear through to 5th gear, cold engine through to operating temp. The stutter feels like a misfire, but no CEL. I have a work van that had dirty injectors due to the servo it was being filled up at, but after running injector cleaner through it the problem disappeared.
I have hit the carb up with throttle body cleaner, (This actually has helped but for limited Km's) I have pulled out the injectors, checked the ring's & cleaned them, & run the engine with high percentage injector cleaner/fuel mixture, (as per my work van) but the problem is not going away.
I now have 1 more week before having to hit the mountains with a trailer on the way home & am in a bit of a stress about this.
I have checked about getting new injectors, but no one stocks them & I am looking at 1 week to have them sent away to get rebuilt (Not an option as we still need to get around)
I am considering flashing the PCM again to see if it clears up the problem long enough for us to get home.
Any suggestions would be really appreciated but also take into consideration that at pres I have limited tools. Once I am back I am able to do any work you guys think may help fix the prob.
