Recently my car decided to throw some misfires at me. Yes, that's not right, not 1 or 2 misfires, but every cylinder. Idle, car has a very minor miss, WOT car has no misses, but while cruising or under some kind of load (other than WOT), car misses like crazy. According to my aeroforce, the misfires are scattered across all 6 cylinders. Everytime I feel it miss, I see on my wideband leans out to 16.5+.
Now I've thrown a few parts at it to see if anything helps.
- ICM, no change.
- OEM Plug wire, no change.
- New AL104s, no change
- Coil packs tested for continuity and resistance, all checked good.
I'm started to tend to think its injector or fuel related. My next step is to (hopefully) replace the fuel filter. Keep in mind, Im running stock injectors on my setup (in my sig), so I'm thinking my injectors are finally crapping out on me? Odd they all are at the same time though. I'm also going to check the injectors for specified resistance.
Curious if anyone has any ideas before I start throwing more money and parts at it.
