1992 Cadillac DeVille 4.9L Poor Idle Quality, MIL Lamp on, no power
At idle seems to have misfire and low idle, under load it has no power or pickup. Injector pattern looks good and quad driver is compensating for load. Driving test coming down to stop it wants to die out. Sequential injector killing has been done through cars...
