Message replaced all 6 injectors last year. did a check on the ptu. i did an ohm test on the ptu not sure if it is the way to do it but e1 was 55.6 kohm e2-44.1 e3-82 e4 126 E5-128 and e6-85. are these even useful? i know in the manual to do a continnuity test for the ptu but that also didnt work. it doesnt miss horrible and it doesnt seem to be any one cylinder. hard to find that out with such a small miss. can hear it easy at idle just a little burp. driving constant speeds you can feels a little jerk as if it missed. for cleaning all the conectors what do you guys use? any other ideas?
