my daily driver URS6 avant needed a clutch recently so i installed one. did not touch anything else in the car. car ran perfect before i took it apart. now since i put it back together the lambda control decides to either turn itself off or when it does become active it will stay around 14.7 for a short period than the requested AFR strays way off to like 25AFR and wont recover from it unless shut off and restart the car than the process starts over. when the requested AFR strays off the car is not drivable at all till shut off and restarted. never seen this problem before even and i've been fighting with it for 4 days now.
for more detailed info my load is around 19-20 at idle with the engine at operating temp. injector constant is set to 632 at 3bar fuel pressure though i have 630cc injectors but close enough. when lambda control is shut off by setting that map to 0 requested AFR goes to 14.6-14.7AFR and car idles at 14.4-14.7AFR. no vacuum leaks in the intake as vacuum in reads perfect in the ECU and it was smoked tested. im using zeitronix ZT-3 wideband controller with the simulated 0-1V output for my lambda sensor. i tried disconnecting the wideband and putting an OEM bosch sensor in its place with the same end result. not sure what to do here and any input would help.
