Jeep runs fine for abt 10 minutes then kinda sputters, but doesn't loose power. Had diagnotic done and it said 1st injector firing improperly. Mechanic said this is not a typical problem on jeep, and would need time to properly diagnose. Suspects it is the computer, but says this is not a common problem on jeeps. Have has stalling issues in the past, replaced: throttle position sensor, coil, crank shaft sensor. Any ideas or advice? I'm a girl and need some advice, thanks!

How are the other injectors firing? Did your mechanic try a know good injector ( from another cylinder ) to see if it is a driver problem or an injector problem? I have seen a lot of issues with the harness on the 6 cyl Jeeps. It could be a frayed harness, from oil leaking on it. Good Luck!
