B16T dumping fuel off throttle
Random issue, up until a week ago my car ran great it's a stock b16 on 10psi tuned on chrome.
The issue is not always happening sometimes it's back to perfect. So Normally off the throttle means no fuel is going in , wideband 18+, When I give it some light boost or sometimes normal driving and let off its burps and pops wideband flashing 10-12:1-18+ it won't stay off the gas. Back on the gas numbers are ok. Sometimes they aren't and jumping. Next I'll go and be idleing the car suddenly dumping 10:1 until I wait or rev it till it figured out wtf .
Like I said this just came up, changed plugs cleaned tb swapped map sensors. Injectors cleaned last season 680cc.
It's a drivability issue flooring it is totally fine.
Next step? This is preventing some racing I'd like it sorted out. Compression timing everything is good. Tps? I will check.

Re: B16T dumping fuel off throttle
this would change after 2 years no problems? it happens at idle sometimes as well, and sometimes the driving is not good either. it effects the entire operation at partial throttle. I cant figure it out. problem is intermitent
last hope is the tune shop

Yuuuup a good old t tap from my nitrous days was the culprit . Car runs great again. I'm using a tb without a fitv now since I swapped it to troubleshoot I guess it doesn't matter
