Bad FICM?
Originally had half working injector 4, verified by IDS uncompensated test. Replaced injector 4 and upon start, no fire on cylinder 6 (never had issue with 6 prior to swapping 4). Got cylinder 6 contribution code and IDS uncompensated confirmed no fire on 6. Drove 100+ miles to purge air and still no change.
Replaced Injector 6, now intermittently getting codes from Cylinder 8, 1, and 3 contribution codes. Sometimes coming to a stop I can feel it not firing on all cylinders.
Have verified intermittent no fire on 8 (IDS uncompensated) when the problem occurs.
In short: problem on 4, replace 4; new problem on 6, replace 6; new intermittent problem on 8, 1, and 3.
What do you fellas think?
