klze misfiring, bogging, backfiring
klze misfiring, bogging, backfiring
i went to the tracks with my ze the other night. everytime i floored the gas, once i hit 6000 rpm it would bogg down and backfire. i would have to let out the case and then floor it again but at 6000 rpm it would happen again. my friend spectating said i had a lot of black smoke from my exaust. it only happened at 6000rpm and up. i adjusted my safc 2 to lean out the fuel mixture thinking it was to rich but it only helped out a little. could this be my timing or does anyone else have any suggestions. this never happened before an i assumed it must be timing cause i just serviced the water pump and timing belt. thanks for your help

Re: klze misfiring, bogging, backfiring
is there a way to disable vris so that you've got max airflow at all times? or is it better for it to be on?

Re: klze misfiring, bogging, backfiring
with the VIRS on it will give you better mid range power but with them off you will get a bit more up top but every thing i have seen says keep the VIRS there cause you will lose alot in 1/4 mile times and that means you dont gain anything

Re: klze misfiring, bogging, backfiring
The VRIS ensures you get maximum airflow by tuning the induction tract to minimise inertia effect on the moving air.Originally posted by ZEmadman:

Less inertia = More air into the cylinder
Re-shaped and re-sized gearshift lever. Best driveability mod you can do!

Re: klze misfiring, bogging, backfiring
i had a similar problem. the car would stumble at about 5000 rpm and then it'd accel fine past that.
I replaced both O2 sensors, and now the car runs flawless.
