When I'm on full boost...

0201- 2nd gear slush misshift
0604- ignition circuit
1107- 5th cylinder misfire

i reset it, went boosted carefully... and it did the same thing a while later... any ideas and how they're all related...

I know my tranny's dying... which would explain the misshift. I read the plugs, all are normal, brown

 

5th cylinder misfire.. Could be one of your coilpacks starting to go bad..

 

how's your plug gap?

 

Take this info whichever way you want, but as I posted in the "spark plug info" post, Z's stock are .40 gapping, when going w/ more boost, most people go w/ a colder plug + regap to .36.
Maybe you should do the same. Provided you have a colder plug already, maybe regapping to .40 from .44 if I'm correct, that should help some.
My rougher idle went away when I regapped.
Hope this helps some.

 

.36

 

Well no wonder. It's amazing your car is running at all. Your gap should be .036, not .36!

 

That's what I meant... I always get those confused..

I shouldn't complaing w/ 400 hp should I.
(thanks for the correction)

 

yeah yeah
