Hey guys just bought a 07 trooper. Previous owner stated it ran great etc prior to clutch job then had issues. I drained tank, replaced plugs etc. found one of the injectors connectors was not connected and plugged it in. Solid 50psi fuel pressure. It starts easier than previously on 3 cylinders but still runs very very poorly. I’m thinking the sound I’m hearing is it detonating at around 3k. It kinda sputters and falls apart. Sounds like clicking or something when it happens. I am at a bit of a loss, compression is a solid 150psi across the board with no movement. Verified spark and now am assuming all injector are functioning more or less correct as if I unplug any one it sound terrible at idle.
A note, I tapped plugs at .7 manual called for .9-1.1 but that seems super over doing it but I will try adjusting them to 1.0
additionally I’ve noticed the fan in rear doesn’t turn on.
anyone with any help I will be in your debt.
