'02 7.3 miss, AE test results ok
2002 F350 7.3 185k. Motor has a miss, not horrible but slight truck vibration and you can hear it well the exhaust. AE tests, Buzz test all individual solenoids buzz, some more than others for the various tests but all in the 700rpm to 900r range.
CCT test has come back test successful every time with no codes. The change in rotational velocity check comes back with all cylinders besides 2 and 8 at or near 0. 2 will read up to the high 1's and cylinder 8 I have seen after racing the engine up to a 3.6 At normal steady idle it's usually around 1.7-2.7 with the infrared temp gun those 2 cylinders are usually cooler although cylinder 8's temps will fluctuate wen sitting at ilde.
Codes present are p1280 ICP sensor circuit low (it has a new ICP and harness). Runs around 480psi at idle. It reads 53psi with the key on engine off also which I thought should be 0. P0113 IAT circuit high input. Replaced the sensor because the guy had some box jumped to it. It reads within 3degrees of EOT when cold so may be an old code. And P0605 Internal control module KAM error which I think is just saying the PCM has had work.
IPR is 9.37% at idle. MAP and EBP are within .1 degree. The BARO sensor reads about 4.6v and hardly ever changes and is red, but I've seen that's equivalent to 14.7 psi so should be right. New fuel filter, injector ORings, Glow plugs. There is one phantom blue wire coming off the engine harness not connected to anything but haven't been able to find what it goes to. If anyone has any help, please let me know. CPS looks newer and is the black or dark blue
Bad number 8 injector? Bad UCVH?
