Hi,

I am starting to experience a series of sensor failures. I am not sure if this is truly sensor failures, or should I look at the wiring harness. It all started when the car started running very rich. Any comments?

Start by plugging obd2 and look for codes if it is throwing any

That would be your MAF sensor. Is your CEL on?

i'm having the MAF sensor replaced on my 300ZX, very pricey for OEM.
had nissan run diagnostics and that's what they came up with.

First I would like to thank all of you for responding. Yes the CEL was on, using the code reader I replaced the MAF, code went away. New code was P1121 for the electric throttle control actuator or the Throttle Body Component. I have only one code showing on the reader. If there are addtional codes I will look to see if there is any way to see them.

It looks like I will be purchasing a new Throttle Body next. When I replace this I will clear the codes and add any new information.

Did you try cleaning the throttle body? Most people start having issues after they clean it.
