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.

 

Its the decel parameters. Contact your tuner.

 

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

 

Tps wire broke.

 

yea it would either be the tps or decel fuel fut was somehow turned off in the ecu

 

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

 

That coulda cost me a run

 

Whats the setup?
