1996 240SX. I kept getting the code for Mass Air Flow, forget the exact code. Anyway, went ahead and replaced the MAF and while the car starts better and idles better, it doesn't feel exactly like it did before I was getting this code. I finally got smart and grabbed the multimeter and checked out the connections. The one thing I read was that pin 2 in the harness for the maf was to read 5 ohms. I'm reading 3.8 ohms across this. Should I be worried or does it take time for the car to adjust to a new MAF? I know when it comes to speakers, when impedance is rated at 4 ohms, a speaker is going to read 3.2 because of the frequency at which the meter puts out, so I take it 3.8 acceptable and all I need to do is drive the vehicle more and let it sort itself out?
