I pulled the connector off of the sensor and there was no corrosion, it that is what you are thinking.
<are you getting a CEL/SES at all> I'm assuming you mean error codes. No, the ECU is not displaying any error code (check engine light is off). The dealer said that they did a rolling test (??) and the error only showed up then. Which doesn't jive with what I'm seeing (the "bad idle" happens every 5 to 10 sec while in a gear and at a standstill).
I have the "magic" sequence that turns on the OBDII diags (blinks the engine light w/ the error code). I'll try that and see if it spits out any code.
I dread calling Nissan CS. the muffler rotted out at about 35K and they wouldn't cover that.. after several hrs on the phone in the span of a few weeks.. But you are right it doesn't hurt to ask---well it hurts a little
...
do you think a bad---or going bad ...MAF sensor would display this kind of behavior??
thanks
