hi all,have not got the cel light on when driving but funny issues with car so thought i would do a fault code check.
my results were a throttle position sensor and afm.
are these fairly common issues and would they cause the cel light not to come on whilst driving?
and also would they cause my funny idle and missfire issues?
cheers
tim

 

anyone?

You will get a better response if you either list your car in the 'garage' or post up your details.

Are you sure you read the codes correctly, the MAF (23) will cause idle/running issues, but the main culprit for decreased mpg is a failing o2 sensor (32) which is only 1 flash away from TPS (31).

I would reset the ECU as per JGM's instrucions which will clear any stored faults, then go for a run and do another diagnostic check, this will give you another chance to count.

 

tps common fault on most makes models will cause erratic idle
