well, i replaced the cat, regapped the plugs, replaced o2'*, and put a cai on, and i still have the popping. the popping occurs under heavy load, in the middle of gears. on the top end of the gears the popping disappears.... later today i am installing a performance plug wire set, and an intense pcm to see if it helps any. I am not sure if it will help, but the intense pcm will make the car more fun.
i also have been experiencing KR in first gear starts at 0 works up to 1, in second it is 0-1-2, then when it shifts into third it is 2-3 and i haven't held WOT too far into third, as i would have to drive over 100 to check this out.
please post any thoughts as to either issue of the popping or the KR
thanks in advance
