High Lambda Reading V6
I am using a 3.0 V6 engine from a 2002 166 in a kit car, the original car was 2002 CF3.
I previously posted a question regarding post cat Lambda's, thanks for the replies, I have since had bosses welded into the exhaust for the additional probes.
Set up now is:
156 manifold- pre cat lambda (about 3" from manifold)- 200 cell sports cat in silencer- post cat lambda after silencer. Separate pipes for each bank.
Induction side is as it was in the 166 apart from the addition of a K and N filter.
I'm getting high (lean) Lambda readings on the emission test, too high to pass an MOT:
CO is 0.2 Lambda is 1.044. Very similar on both banks.
Ive checked for air leaks around the throttle body and plenum and cant see anything obvious.
Last week I fitted 2 new Bosch pre Lambdas without any difference. Everything seams to be running as it should, start easily enough, gets to temperature, fans cutting in/out etc.
Ive plugged in diagnostic and get the following error codes:
P0433- EVAP circuit.
I don't have EVAP control valve fitted
P0650 - MIL Circuit
Indicator light error. I don't have indicator light connected
U1706- CAN Network (NCM NFR)
Error in communication with ABS. I don't have ABS unit fitted
P1314 Vertical accelerometer/Uneven road surface
From what I can tell this is a sensor in the 166 to do with the car driving erratically.
If I clear the codes disconnect the diagnostic/reconnect the diagnostic same 4 re-appear without starting the car so not errors triggered by running the engine.
Apologies for the long post but need to get the emissions to MOT level so I can register the car and am a bit stuck as what to do?
