Whats up guys, so my DD has been acting up on me... DDs arent supposed to do that right?! Its a 2000 4.0 aw4 with 136k. So out of the blue it started to idle a little rough, my tank was low so i filled it up with premium and some lucas fuel injector cleaner. Drove for a few weeks and no issues. Then it comes back worse than before. Jeep was missing very bad while going down the highway, CEL blinking and jeep wouldnt rev over 3k. Thankfully at the exit there was an advanced auto so i scanned it and the only codes were P0300, P0301, & P0304. I was about an hour away from home and didnt wanna pay for a tow so i did a hard battery reset on it and the jeep fired right up and ran like a top? So i drove the hour home, no issues, next day was driving around trying to get it to act up... nothing. Drive it to work the next day and the misfire comes back. So i did the plugs and coil pack in it. Fired it up, still had a slightly rough idle but revved fine and drove normal. Since the plugs and coils i havent driven it much due to work and not wanting to get stuck on the side of the road.... so thoughts?! I wish i had some more codes to point in a better direction. As the CEL has not come back since the new plugs and coil pack.
Thoughts?!
