Sounds like a vacuum leak. Clean the MAFs, pull and inspect your spark plugs, look for any leaks while doing those two things.

 

I cleaned maf,changed spark plugs with oem.passenger side by the firewall had oil in the spark plug well,changed them all out with new oem ones.bought another ecu had Nissan reprogram n do all procedure,changed upper and lower intake gaskets ,changed exhuast gaskets all with oem,changed all four cam sensors and crank sensor,checked for leaks with water n soap,n carb cleaner...car temp goes above normal.then idle starts to raise up to 2k then boom!! Idle hunt ....unless I turn on AC and all the loads then idle goes down to 1100.when car is cold it runs like an animal..I'm so lost !!!!!!!.when I turn on AC I can here if one of the pulleys are going bad IDK ..this is a good one..

 

I’m having the same problem is it the fuel pump cause at the stop sign my car jerk to go like it’s hesitant

 

Not sure.i know it's getting fuel because I just changed upper and lower intake gaskets and gas just poured all over me on a count of I didn't release gas pressure..I hope it's not my head gasket.hesitation only when warmed up.n my scanner say it's going over normal temp.got to figure why it's going over temp
