Truck is a 1999 ranger 3.0 4x4 with manual trans.
It was driving perfectly fine and started idling terrible. Its done this before I changed plugs wires and it was fine.
This time I was in traffic truck has been fine for 5k miles. Waiting in traffic stop and go stop and go it had same idle...
Dug deeper into the truck found a tornado in the intake LOL. pulled that out cleaned MAF and IAC. Had 2 codes on my scanner P0171 Bank 1 too lean
and P0302 Cylinder #2 misfire.
Changed plug again on #2. Checked and verifyed spark on #2 cylinder. Still running rough as can be. I checked the injector and it had .29 ohms so i replaced that. Lean code went away. Still missing. yet no code.
I found a hole intake and plugged it with a bolt it came from oil filler cap vent to the intake. Something somewhere has a vac leak I think... We have spark and fuel. Unless the compression is bad.
Pulled plug and started it and it sounded like it had a lot of compression, wont know till tomorrow.
sprayed carb cleaner all around the motor and nothing changed rev wise..
New intake gasket and
New coil!
Cliffs:
Truck idles terrible and shakes truck violently until 2800 ish up
Coil is good
New plugs, wires, injector
po171 and po0302
plugged intake from oil filler cap
carb cleaner caused no change in idle around hoses
No power... driving me insane
