this is my problem at idle the engine run smooth until i push the pedal and try to hold the rpm at 1200
the rpm go up and down but if i unplug the 02 sensor the engine run smooth again
I read in a another post that if you have one clogged injector it can screw air fuel ratio and cpu try to compensate for the lack of fuel
of this injector in close loop

from this scan does it sound right ?
