    hey guys

    well when i tap the accelerator on my car seems like a little hesitant , but i also was playing around with the car and went to turn it on with the afm not plugged in lol turned it over but didnt start it then i plugged it back in did the ecu reset , then i went for gold !! and for some reason it was reving much nicer and reved alot quicker , turned off the car and turned it back on and was back to slow ness!!

    i cant figure it out !!

    is my timing shit ? , i hate my idle like around 1400-1600 on start up even when its a hot day!

    It takes a bit for the engine to heat up, even if its a hot day. If its idling too high, simply lower it.

    my 2 cents would indicate a bad sensor.

    Resetting the ECU turns back all the settings to factory, then with input from the sensors the ECU tunes itself for best settings. I dont know what sensors have input into the tuning but id assume O2 is a major suspect, TPS, AFM aswell. If it runs great after a reset and gets progressivly worse id think it has to do with something messed up in a sersor

    Haha mines still slow as shit all the time....

    Up to the point of researching diff spark plugs, testing the tps, and double checking cam alignment and timing again, on the diff engine strokes...
    And hopefully get my TVIS working one day.....


    anyway, goodluck man....
