I recently expanded my ATap logging to include # of misfires on each cylinder and shows on occasion on no particular cylinder 2 - 4 misfires. Mostly at idle. Is this normal?
Thanks, Randy Hughes

 

any mods done to your car?

 

I wouldn't think so-- check your plugs and wires <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

 

No, its not normal!!!

Check everything out!! and then re-atap!!

 

Aftermarket Cam?
POS GM Platinum plugs??

 

I will include sig...I still haven't shortened it. I am not getting a lot of misfires. I have replaced wires with Taylor spiros and plugs with NGK. Idles perfect and runs strong. I did notice a couple of the plug wires are approx. 1/4" from header tubes. The Taylor wires are supposed to have add'l heat resistance?
Thanks for any suggestions.

Mine is basically stock and I get misfires during idle .. runs fine and strong. I think that`s normal
