Update to the 08 spec b
the the elusive P0301 and P0304 has returned. The only time I get the CEL condition is when I put the car in first gear or reverse apply gas and let out the clutch.
I also can notice a ruff idle when I push the clutch in and come to a complete stop. Idle is ruff for maybe 3 seconds when the car has stopped moving and then something adjusts and car smooths out.
The new injectors, MAF clean helped out tremendously, the car rips now except when I hit the two above conditions.
Could O2 sensor cause it? Has 109k on the clock and they haven't been changed. Also was thinking maybe fuel pressure regulator.
I did notice a drop in mpg with the new injectors from about 25-26 mpg too 23 mpg. This seems like a good sign to me probably a little to lean before. But still didn't cure the pending missfire problem.
