!HELP! MY MAXIMA DOESN'T IDLE UP WHEN I USE A/C, HEADLIGHTS, ACCESSORSRIES, ECT.

1990 SE A/T

IT'S DONE THIS FOR A WHILE NOW, AND IT'S GETTING OLD. :slant:

AND THE HAYES REPAIR MANUAL SUCKS A BIG ONE

sounds like a computer issue. get a code reader and see what it says or even call a nissan dealer and ask. people need not be afraid to ask service guys questions, they might tell you over the phone!

I READ ABOUT A fAST IDLE CONTROL VALVE IN THE HAYES MANUAL, BUT IT DOESNT SHOW WHERE IT IS ON THE VG30. IT HAS PICS OF THE 88 MOTOR., COULD THE THROTTLE POSITION SENSOR BE PART OF THE PROBLEM?

Maybe the alternator is going out??

I second that.

Alternator Is 100%, No Dive In Voltage When I Use A/c, Headlights, Accessorsries, Ect. I'm Gonna Ohm Test Most Of My Sensors And Control Valves( Idle Air Control Valve,tps,maf. On Thanksgiving.

Maf Is Good, And The Tps Is Toast - Has No Ohm Resistance At All.

I Cant Find The Idle Air Control Valve On My Vg

TPS : I sell those
IAC is by the throttle body (piece where your accelerator cable connects to. right by the TPS

you can test your tps in "switches on\off mode"

IS IT IN THE THROTTLE BODY, OR UNDER IT? AND THIS IS THE VG WITH THE THROTTLE BODY FACING THE FRONT OF THE CAR.
I TESTED THE TPS WITH A FLUKE 18 AUTOMOTIVE METER. NO OHMS AT ALL, DEAD.

internetautomar HOW MUCH $?

YGPM
IAC motor is the right (drivers side) of the TB and its on the intake runner.

Oh My God My Caps Button Is Stuck Plz Help!!!!!!!!!!!!

I had the same thing happen. Just idled hard. I do miss it.

could it be a belt problem? In the winter they could be getting cold and stuck.

The IAC is toast, resistance from connectors 3 to 4 is gone. time to spend some $$. and I adjusted my TPS and my car is faster on the take off, with no stumble
