Car- 01 Z28 with ported Heads(10.8-1 comp.)TR 224 on 112 Cam. M6

Have done the normal stuff,Raise rpm to 950 set misfire test at low rpm to 32000 and have tried different idle timings.Car idles and starts great but after idling for awhile(traffic) I will get a misfire code.Checked the misfire and they are on all cylinders at idle.Not many 10-20 each test,but enough sometimes to trip the code.While driving there is no misfires.

Anything else I can do?

Thanks

 

keep playing with idle and low rpm tables
you will just have to keep raising the value
I have seen multiple tables around 32,7xxms
before the code does not register

 

You could always turn the code off.

Only if it just the P0300 code though.

You still have misfire monitoring on each of the individual cylinders and misfire counting. You can watch either of these if you ever have a problem.

I was thinking of deleting it,but the car needs to go for an inspection sticker which they plug in.I thought there scanner will pick up a deleted code <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

 

is your motor loading up? what are your o2 readings?

true too. your iat sensor may be adding more fuel to compensate for your tropical temperatures you are seeing there. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

you might e-mail nogo, he seems to be the sharpest with pcm tuning i have seen here yet. <img border="0" alt="[worship]" title="" src="graemlins/gr_hail.gif" />
