i pulled the driver side injectors to replace o-rings, put them back in, when i started it back up, it started rough, like normal you know, getting the **** out of the cylinders, then when it cleared up it was still missing. like maybe if you ran out of fuel and were trying to get the fuel back to all of the cylinders. i tried to ride it out, but never cleared itself up. so i get back home, take the heat gun and point it at the exhaust, the passenger bank was at 64 degrees and the driver side bank was at over 300 degrees.... after running quite a while. i cleaned the idm out, bc i do go into the woods quite a bit, i changed the passenger uvch. still doing it. i am not sure how much an idm is nor am i sure on how to test one.... what do you think?
