SR running too rich out of nowhere

[starkos14]

so I'm having trouble figuring out my issue with running rich. here's the story if it might have anything to do with the problem. my clutch died and my car was running perfect. so we pulled the tranny and i ordered a new clutch. during the clutch install. the car had the battery disconnected for 4 days and we almost completely dropped the subframe due to my solid motor mounts. so we get everything back together and i go to test drive the car with the new clutch and before i know it, the car is hesitating. i let the car warm up first btw. and now im just pouring black smoke and fuel. my plugs died. i cleaned my coil packs, tested them and all the plugs were replaced and they all get spark too. i checked the afc if i was getting signals from the maf, and they looked normal. so i dont think its the maf. i pulled the fuel rail and checked to see if any of the injectors were leaking, and they weren't. this is basically where i am right now and im still pissing gas out the exhaust. im sure its not oil either. sputtering is between 2500 and 4500 rpm. driving or revving

my current setup thats relevant to this issue:

t28
550cc injectors
z32 maf
daughterboard chip for z32 maf, t28 and 550's
apexi afc neo for fine tuning

What happens if you unplug the maf? Also, make sure the ecu is ok, check to see if the daughter board didnt come loose, it almost sounds like running on an ECU with no rom. If you have a consult hook it up and pull codes, see whats going on.

[starkos14]

no consult. and idle gets rougher without the maf, so im sure it works. i agree about losing the tune, but only static electicity would erase the daughter board tune. and i doubt it came loose. ill check tho.

check ECU for Code and check you CAS it might have died mine just recently did for no reason

flow test injectors.... i bet you got one sticking

[smelly240]

check all of your couplers - maybe a leak?

[starkos14]

injectors are fine. no loose couplers, the car actually runs better when in boost. ill be checking the codes next

[starkos14]

so ive been doing all this reading on my car this past week and i finally go to check my engine codes at my friends house where my car has been, and my one friends came along to check out the situation. the car fired right up and now runs perfect. and i didnt do shit. wtf... next time this happens, im checking codes right away. i think a sensor is probably about to go.

[starkos14]

so the problem came back... went to check codes and my mines ecu doesnt have the led... awesome. replaced the cts and i still have the problem. any other ideas?

[Megadang]

O2 sensor? I had a similar problem, and the car sounded like a WRX. Spraying gasoline out the exhaust. I replaced my O2 sensor and it ran fine afterwards.

[starkos14]

btw, im sure its a sensor issue

[starkos14]

i guess its time to try that next
