Running lean would run hotter but your fuel trims don’t indicate that and you don’t have any fuel trim faults, all your ***** new and both banks seem to be balanced. Your in SoCal there should be some good shops down there but remotely (and not a Nissan specialist) I’m drawing a blank.

There is one thing i noticed after i had the ac system recharged by a shop i trust and go to all the time for things i cant do at my apartment complex. After they evacuated and then recharged my system when i replaced my radiator i get cold air, but not as cold as before they serviced the ac system. When the rpm on the car get up to about 2500 though it finally starts blowing very cold air like it did before the ac service. Not sure if that’s an indication of anything or that they just didnt service the ac system properly, but that’s the only other odd thing i can think of.

Check your A/C for a leak. One of the o-rings at a connection may not be right.

Anybody know if it’s possible for drag from the ac compressor to cause overheating? I’ve seen mention of this on a few other car forums and just finished watching a video of a mechanic replacing an ac compressor on a 370Z and mentioning that the ac compressors on our cars go out quite often.

So i did a little test and set the ac temp to outside ambient temp at night after the cabin of the car had cooled off.....ac clutch never disengages even after 10 minutes....is this normal for our Z’s?

Probably. A/C runs most of the time to control humidity.

So I found something interesting....it seems we inadvertently performed the mixture ratio self learning reset procedure when we unplugged both the MAF's, I'm wondering if the computer on this car stores the fuel trims in a non volatile memory section of itself? as the FSM doesn't seem to list unplugging the battery as a procedure to reset the fuel trims



Also I've been keeping track of the fuel trims since after we unplugged the MAF's and over the last week of normal driving with a nice long trip to start off with and this has been the result....



No more gas smell after leaving the car sitting like what was happening before and haven't had an instance of it semi-stalling in this last week since our accidental reset procedure
