2006 Grand Cherokee Misfire

Hello Everyone

I have a 2006 Grand Cherokee 3.7L V6 with 88K miles on it. The wife was driving it yesterday and the MIL came on solid while at the bank. She started to get a vibration from a misfire on the motor. I went up to the bank and realized I needed to get it home if I had any chance of fixing it myself.

On the way home the MIL started flashing and beeping at me. My Jeep went into Limp Home Mode and engine would only go up to 2000RPM. Called a buddy with a code reader and it showed #5 injector was malfunctioning. We shut off #5 with the scanner and it had no change. We shut off #3 and the motor almost died. Today I got the injector, tore it all apart and replaced #5.

Well, still has the same issues. Still has a rough idle with misfire as well as the MIL still illuminated and in limp home mode.

I have no idea where to go from here and hopefully the dealership will be the last resort. Any help would be great and I am no mechanic lol

Hey there, while this is a grand cherokee forum, it's the forum for the '93-'98 ZJ. You'll have better luck posting over in the WK Grand Cherokee forum over here: http://www.jeepforum.com/forum/f67/

If you're lucky a mod may come by and move this thread for you.

1998 ZJ Platinum Limited 5.9, New engine and trans, no front driveshaft, but it's pretty
