370z HELP

Bigchillin · 03-08-2018, 12:22 PM

My air fuel ratios are showing that I’m running lean on heavy throttle. I’m also going to check my crank position sensor.

Fix the exhaust leak and get a new 02 sensor first. That's the most likely reason for what you're dealing with.

Edit - are you running stock cats? They could be plugged up. They don't like turbos.

Also, from what my mechanic is saying is that it's isolated to one cylinder which is cylinder 1. Something is going on with that cylinder.

Bigchillin,

I had to revive this thread... Did you ever find a fix to your problem? I’m having the same problem.

Thx for the help

I've got $5 that says it's the cats. DIGItonium had the same symptoms forever, and it was the cats.
