[QUOTE="94forddiesel, post: 687552, member: 10607"] its a 2008 f250 with 150000 miles dpf delete mini max and s&b intake. i was on my way to work one day having some fun messin with a cummins running it up pretty high and when i got to work i was letting it cool down then it started to have a mis and the check engine light came on. it said cyl 1 misfire and cyl 1 contribution. cleared codes and after work headed home plugged the solus in and check codes and did contribution test was showing cyl 1 was off so i replaced the injector then no check engine light came back on. plugged solus back in did a contribution test again and was still reading a little off for cylinder 1 so far all i have tested is cylinder 1 compression and it was around 200. did not test any other cylinders yet. was wondering is that too low? what else should i test / look into thanks for any help!!!
