Just out of curiousity, have you put your ECU into Diagnostic Mode & checked for Trouble Codes?? See your Factory Service Manual for the procedure. If by chance your car is throwing a Code, (Or Multiple Codes), check the Grounding point on the driver's side of the motor directly above the Oxygen sensor. If your problem is NOT with your ECU or MAF, then chances are you have a short in the ground wire on your engine block. Nissan ran several ground wires to this point on the engine block. If one goes bad, then chances are it may affect the others. I had this problem on my 95 S14 years ago & it turns out my problem was due to a bad ground on the engine block.

Anyhow, hope this helps...
