Mass air flow sensor nightmare

[godannyc123]

I have been having problems with the Airflow sensor 1998 maxims SE. At first I though it was the sensor I replaced that and it is worse than before. Before if I touch the plug the plugs into the back of the sensor it would work sometimes? If it rained or it was wet it would not work. I am trying to find a replacement plug Nissan does not sell just a plug they sell the whole harness(NO). Gone to embay and still looking junkyard next

ANY SUGESTIONS I AM LOSING MY MIND!!

Sounds like a exposed wire issue. Check and make sure you don't have exposed wires leading to the MAF pigtail.

I HAVE CHECKED FOR AN EXPOSED WIRE LEADING UP TO THE MAF SENSORON A SNAP- ON 3000 THE MESSAGE I GET

MAF SENSOR OR VAF?

MANUF CODE P1320

CAN YOU TRANSLATE

IT RUNS BADLY WHEN I UNPLUG THE MAP IT RUNS A LITTLE BETTER NOT MUCH? STILL NOT RIGHT ANY HELP WOULD GREAT

p1320 is ignition signal primary. Meaning one or more coils is dropping out. The maf code is likly a result of you unplugging it while it was running. Unless you get a specific cyl misfire code it will be next to impossible to figure out which coil is dropping out.

Yep, Good old P1320 is the Ignition Signal Primary. As NISTECH has stated, it is nearly impossible to pin-point which coilpack it is that is causing it. Your best bet would be to replace all the coil packs and go from there. They can usually be had at a dealership for around $125, that is what they charge at our Parts Department. Good luck.
