V6 Lambda Sensor
Can anyone give me a definative answer to tell if the lambda sensor is at fault please? Does a dash light appear etc......
I have probs with eng cutting out at junctions etc occasionally.
Just replaced battery as previous one was only at 12.1v, so was thinking it was a little tired when running heater, air con, lights etc, which may cause it to struggle when coming to a stop.
Also can the M.A.F be unplugged on a v6 and run to see if it's any better. Performance seems fine but fuel economy is affected i think.
Exhaust system is all new as well, so not blowing.
