hey guys i have been having issues with my air fuel guage it goes to red or off when at idle after it is warm and also the guage will go from running stoch to bouncing erratically and can feel power lose at around 1500-1800 rpm the will come back. i hope this makes since. it seems to have magnified after cc306 install and madz tune. I know the tune is good due to it was doing it before it just seems to have gotten magnified. i was thinking the tps is going out, and also if i let completely out of the trottle it dont show and ratio untill i hit the gas again. but anyways what you all think,

 

Are you using a heated O²? If the sensor gets cold at idle (like mine does), it won't generate.

 

im using the factory ones
