Injector 6 and 7 issue. Lbz

[Sethdavis09]

On start up truck runs smooth, after you drive it around it shakes at idle. Has p0207 for injector 7.

New fuel filter
New injector 7 pigtail. (Previous pigtail looked to have been cut and reattached but not replaced)

Balance rates show 6 and 7 at 12. Rest are within 4+-

Seems to happen once under load. You don’t even have to drive move 5 feet at idle. Will run rough until restarted.

What we thinking? Currently has hotshots in it as well.

Try ice picking those two connectors. If it works then plan on replacing them. If not then you are going to have to ohm out the harness and see if there is any breaks. My need to load test the harness too
