MAF ??

[Mike in Texas]

Still trying to figure out why my 90 is running rich ( see post "S/C codes 42&92"). I have a C&L 73 mm (calibrated for my 24# inj) and the sensor is measuring .88v at idle (~850-900 RPM) could that cause the rich condition, codes42&92, missing on acceleration @ low rpms?

What sample tube is in the housing?
What sensor are you using? part number?

Your sig says 76mm ???

Thanks,

Thanks for the feedback. I apologize but this thread is also going on at Supercharger codes 42 & 92. As for the C&L it is a 73mm. Thanks for catching that, I changed the sig. I'm trying to make sure the MAF is the problem before spending the $ to upgrade. Looks like no way out of a dyno tune.
