Car Runs Super Rich Between Shifts, BOV Recirculated

[NeWyoRksPLaYaZ]

I've had this problem for a while that every time I shift or let off the gas reguardless if im in boost or not, it runs super rich at like 10.0 and I didnt have my bov recirculated. Today I recirculated it and its still the exact same, car runs super rich between my shifts and if im at a high rpm like 3k and I push in the clutch my rpms fall below idle and it shuts off but then once in a while it catches and turns back on. Also after its running super rich if I hit the gas it goes super lean and then corrects itself. I thought these two problems would be gone when I recirculated the bov What else could it be? I also wanted to add when my car feels like its about to shut off, my afr's are rich like in the 11's.

I would try resetting the ecu first and then see what happens.

Im willing to try anything, ill pull the battery overnight and see. thanks

Any other suggestions?

boost leak if the car is shutting off when you are rolling and push in the clutch

Do you have a SAFC II to correct your car from running so rich when your not in boost?

 

[NeWyoRksPLaYaZ]

no I dont, I have stock fuel system. my mods are a fmic, 60 trim turbo, aftermarket exhaust manifold, downpipe, external wastegate, exhaust, fp intake and xs bov(which is now recirculated) and idk if this matters I just put in a mbc .

Ill do a boost leak test tomorrow at the shop and see what the outcome is.

What should I look into for running rich?

Disconnected batt overnight and still same thing

Could your maf be bad. Im suprised nobody else said it.

 

[NeWyoRksPLaYaZ]

no idea, anyway to test it? It does look crappy inside the maf

 

[zcoh2gdsm]

no fuel upgrade with a larger turbo? do you have a tune?

Check your throttle position sensor for proper adjustment. The 2Gs also keep their idle switch inside the TPS, its something to check.

I have the same exact issue as the OP stated. I have a CBV(resirc) and a EWG(vented). I also have a big leak from my oil-catch can that needs to be fixed. I would try making a BLT(boost leak tester) and do a BLT, your car can throw away the metered air the ECU is thinking that is going in or, pull in un-metered air also. Worth a try.

+1 on the boost leak test, make sure ## BOV is on right, and if someone else installed the FMIC for you check that out first. But if your sure u did it right, check it anyways =]
