hopefully this can assist with some ideas. i have to assume the issue has to do with the turbo inlet install. AF sens A = 25 AF sens B = 13.40 AF sens C = 9.10. pic was taken with the car at idle while parked. ran inside the store and came back to a check engine light, left car running.

Means it's too lean. Either the turbo inlet caused it and/or it could be a vacuum leak.

Check your EVAP Solenoid, maybe one of the connections got loose.

well that vac line wasnt the culprit..still get the check engine when i park and leave the car running. after resetting the code then A B C trims start at zero and A and C sit at about 18 at cruise and B sits at 9. then they all climb when the car idles.

Make it easy for yourself and pressure test for leaks(aka boost leak tester) along with soapy water. Did you remove the intake manifold for the turbo inlet install? Check maf sensor as well if you removed it.

intake mani and maf stayed in. i just removed the bov lines the vac lines and the turbo. replaced with all new gaskets in the exhaust.i have to assumed its something in the back of the engine near the turbo since everything up front looks good. so how do i leak test? just spray soapy water on the connections at idle and wait for suds?

start by pressure testing your turbo inlet . its possible from clamp or hose not properly seated . leak on your bypass valve/hose .

You will need an air compressor or tire pump. You can either build a boost leak tester or simply just buy one. Buy a bottle sprayer add water and soap then spray. If you own a boosted car I highly recommend you investing in one it will make your life easier. I find leaks in most of the cars I work on. I use this method along with a diy smoke tester I made to spot all kinds of leaks.

well fuel pressure regulator vacuum line was popped off in the manifold side. reset ecu, lets see how things go. now positive numbers on afr b and c and a only got to 3 on an idle.
