[QUOTE="TARM, post: 287486, member: 578"] I have a stock IDM. Before I did a HPOP swap I had written the idle issues off as a bad IPR or possibly ICP sensor. But then after about 40 miles with the new HPOP giving it time to shake out any air it still ran rough. The idle has a bit of a romp so I guess its possible that it could just need a bit more ICP or a tad less PW or SOI. THe issue though after running these tests is the fact I have a stock IDM so I should not be getting a P1316. That has to be either an IDM which was fine before I did the upgrades or I would think something with wiring. What I do not get is how loud all the injectors sound off on the buzz test. I can not afford to take this thing on my trip with my family and have it go tits up and I certainly do not want to do any damage to the engine itself or the injectors. Any help you guys can give me that could pin point the issue so I do not have to go digging around would be very helpful. I just do not have much time these next days to spend hanging off the front end digging into the engine. From the test results I am getting back issues on both banks. That makes me thing its likely not the UVCH as what are the chances both came loose? Or is it? The fact that I was under the VC and installed the injectors does make me wonder though. I never touched the IDM at all. I will see what ICP is at idle as RPMs are bouncing at about 50 rpms spread unevenly. I guess it could be the main harness. Any ideas?? [/QUOTE]
