My new set of STI plug wires arrived but they tuned out to be all bad. I measured the impedance or resistance of each wire. One wire was over 13K ohm, and another one was 11K ohm. I ended up returning the STI wires. I am placing an order for a Bosch MAF but it wont arrive until next Monday because of the president day holiday. I am suspecting that the misfires came from both the bad wires and bad MAF. I dont have much data until a new MAF is arriived. I am going to use my other set of NGK wire and their impedance is very good. Each wire is below 1K ohm.

Best4x4,
My D2 has been sitting for a few days, and today the idle code P0505 is gone, but the original MAF code now comes back. My question is now what are the differences between a good used Bosch MAF and a brand new Bosch MAF? The car seems to run very well with the used MAF, but after 15 miles, it threw an error message " additive adaptive mixture correction TRA Bank 1 and 2 Drive Cycle A and B" which is a MAF error
Do I have a MAF issue or it just needs to be reset with a Nanocom. This used MAF has been on the car for the last 50 miles. I am not sure if the car ECU has learned to work well with the used MAF as yet.
Will it make any difference if I buy and install a brand new MAF? I dont know if it will.
Both the new and used MAFs will need to have adaptive value reset. I am not sure if Nanocom will reset the MAF. Have you ever had to reset an old MAF?

I am not brand loyal, I would just get whatever RockAuto or Amazon sells and send it back if it does not work.
