    the problem is that when i'm in any gear...when i let go of the gas and engage it again it back fires and a whitish/maybe light blue/grey smoke comes out for that split sec (substantial amount) also in reverse

    also when on idle white/grey smoke comes and goes.....

    i did the motoman break in....however when i first started the car it was getting flooded so i started it with starter fluid and warmed it up then i drove it home (1-2 miles) slowly then it sat....when i got the new FPR and got the injectors cleaned...i went out and did numerous 2-3-4 pulls and letting 4th gear down to about 2k then 2-3-4 again..... it still smokes...i checked the pvc valve but i will get a new one today....

    any thoughts i think it might be the valve guide seals/ but its a 99 si head
    i have a spoon chipped ecu...i know its not the best but it works
    I/H/E no cat
    after market pr4 pistons/rings
    lsv

    edit: der did you build the motor?

    and if you did build it but did not replace valve seals... :bash:

    the backfiring sounds like a timing or fuel issue...
    sounds like its still dumping too much fuel after you let off the gas...

    on and off the throttle is a great way to kill your gas mileage

    is it a real deal chipped ecu with a verified program?
    or is it a "dump mad fuel pr0gram"

    no, but the ecu is supposed to be runing rich so in any case i'm runing rich not lean....as far as i know black smoke is fuel white is oil and blue is coolant.... and my CR is 9.6:1/ 9.8:1

    hmm, i thought blue was oil, and white could be coolant or possibly fuel?

    blue = oil

    white = coolant.

    greyish black on acceleration = fuel

    dont know what the backfire issue is, but the smoke caused by bad valve seals maybe?

    Get a Non-chipped ecu. Problem Solved. What mods do you have that would necessitate a chipped ecu, or tuning for that matter?
