This has been a serious subliminal problem that I have been trying to blame on a poor A/F mixture however I have come to the conclusion that it is most likley something else. The car feels somewhat slow in general (Low end power has improved noticeably when I found the correct A/F screw position), not the powerful car it should be. This feeling intensifies 100% when I floor the car into overdrive, it revs but no power, no pull, and sounds as if there is a miss. I have replaced the distributor cap, spark plug wires, and spark plug wires around just before springtime this year. I also replaced the OVP relay to rid of irradic idle however this lack of power still haunts me. I know the M103 packs more punch, I'm almost leaning torward the valve timing. What do you guys think?


Also: I replaced the fuel filter in the past year.
