People's experience with bad injectors
Hey guys, anyone had injectors replaced on a N55 F3x, what were your symptoms?
My f32 started sputtering bad which is constant on idle and on acceleration NO CEL HAS COME UP, has new O2 sensor. Plugs and coils are about 1 and half years old. It starts right up, no long cranks. Just sputtering on idle and acceleration and reduced power. I'm thinking an injector or 2 are clogged or bad, no fuel smell. But want to hear from people's experience. |

Drivetrain malf, multiple misfires and shutoff injectors. Had to be towed... Drove completely normal beforehand except for what felt like a misfire(No CEL) at WOT the night before, drove 5 miles normally the next day before it crapped out on me.

I see, not getting the drivetrain malfunction (at least not yet). Drove it a bit slowly around the block in hopes of a CEL but nothing yet. I'll have a chance to do some datalogs tomorrow evening. Still sputtering and shaking. I'm thinking it's something fuel related but not sure if injectors or HPFP crapping out. Hard to tell with out a CEL, I hope the datalogs will show some clue.

Hey guys thanks for responding. I flashed back to stock and got a CEL to pop up. I do have some misfiring going on pointing to Cyl 2. I'll have to troubleshoot it a bit more to see if its a coil or bad injectors.

Here's a log on idle and giving it gas up to 2.5rpms. I don't know if it shows anything I don't see

So I changed over cyl 2 coil to cyl 4 and the CEL followed to cyl 4 misfire. So I'll start with buying a new coil. Coil overs are about 1 and half to 2 years old. Should I buy that one coil or change all 6?

All fixed. Just glad it was just a coil.
