Feels like Engine is Cutting Cylinder(s)
Under mild to high acceleration it feels like the car drops a cylinder(s). If I'm going 70 MPG and stomp it the car downshifts rev's up to like 5K then feels like it drops a cylinder then continues on to its highest RPM, at this point it runs good. Taking off from a dead stop under WOT it gets up to about 4-5 grand and pulls hard but at this RPM it once again starts sputtering and then acts up. Slams to second gear, gets up in RPM and same thing. Feels like its cutting cylinders. At idle sometimes the car feels like it drops a cylinder and my A/F goes way lean. I'm guessing unburnt fuel?
Here's what I've tried:
-Replaced two coils on cylinders that said misfires.
-Pulled all the plugs and made sure they were gapped correctly
-Fuel pressure good
-Ran logs and sent to Johan, said things were good on his side.
-Going to get a cord for my Trinity to plug into my a/f gauge.
So anyone have advice?
-Maybe Camshaft Positioning Sensor?
Thanks in advanced.
