Hi all, the above car has a code for the "lambda sensor no activity"(sorry left the read out with the customer) which is correct in that at idle and for a great deal of the time the sensor does not switch and is stuck on .25 volts unless I spray carb cleaner into the throttle body however the MAF only puts out at idle 0.15 volts and 0.8 volts at idle which seems too low to me. There are no split hoses or air leaks and idle quality is perfect.
