[markus_74]

dear, sir

want to know which is correct air flow for m40 engine?

bosch 0 280 202 203? or 0 280 202 134? or 0 280 202 135?

and if I install the one of this above which is not correct what is happened?

and I found that some of this have co poti and the other don't , so if I get that don't have co poti how can I adjust? or all air flow is non adjusted parts/restricted part to adjust?

thanks smithy, just try use 134 today, feel vrey good and pull very smooth.

but the problem is the idle and cruising is not good, not smooth, like the choking up.

do you have any idea why this happens? TPS??
