I changed out the stock plugs and wires for some TR6 gaped at .038 and MSD8.5 wires...
Now the cars has a misfire...It's been tuned for nitrous (100 shot)...
Question: Would the gap cause it to have the misfire?
Should I change the gap to .035 from .038? or Could one of the wires be bad.
I have checked and rechecked the plugs and wires and its still there...
Any Ideas..

 

Were the wires used? Mine misfired for a month before i found out i had a hole in my piston... And i had never sprayed...

 

I had a misfire this season intermitent and no codes thrown...found 5 broken Valve Springs.

 

wow, thats a good reason for a misfire!!
