Misfire with no CEL 350z Issues. Can We Fix it? 

Glad you are back with more 350Z content :) I have the same boging issue with my 350Z DE after putting on some test pipe and plenum spacer... It only happens on a specific RPM range and throttle load... Please let us know what is your problem, it might help us!

Maybe gallery gasket problem , vvt does not steady oil pressure.

Those down stream O2 sensors don't care if there's an exhaust leak up stream of them. The ECM is just looking for a steady signal out of them.

Seeing you drive the roads I know is so funny to me

I'm experiencing the same issue on mine. I'm running similar mods, test pipes, y pipe, catback and a Z1 long tube intake. No codes except for test pipes, clean maf sensor and its slightly bogging around 2500-3k rpm. I think it's because my car is running lean with all the breather mods that I have, so I was planning on getting a tune to see if it fixes that

I hate the isr y pipe cus it again has FLEX pipes which will make your car sound raspy or rattle so loud it gets annoying after a week. It’s nothing like drone it’s just a stupid rattle, for performance it’s okay but for sounds omfg it’s top 1 y pipe to sound the worst. Go with a straight pipe y pipe with no flex pipes like stillen,dc, or z1

Where do you put the sensor for your afr?

Z contentttt 🔥🔥🔥

For better penetration, you can cut a V shape in the cracks, and fill the V with weld.

My boy smashin thru the roads haha

Come on Alan, as an engineer, you know you should have drilled the head and tail of the cracks. It'll continue to crack under your welds.

Coilpacks are bad

its the gaskets, its the same thing that happen to my 350z

runs crap bc of the vq engine

Skids!!!
