I have a 2002 Maxima and have been experiencing stalling issues. It's fine when you're driving down the road up until you come to a stop. I usually have to have the left foot on the brake and the right foot on the gas to prevent it from stalling. I thought it was the mass air flow sensor because when I removed it, the 2 metal prongs were rusted out that they were broken. I plugged it back in and turned on the car and then went to unplug it while the car was on to see if it would turn off and it did. I tried to see if it would start with it unplugged but it didn't. So I don't know if it's a good or bad MAF sensor or something else. I've also thought it could be the camshaft sensors since one leaks oil due to the O-ring.

 

This looks like a typical MAF problem - that's what was happening when my MAF went bad. The rusting you observed also suggests that the MAF is bad. Re starting with the MAF unplugged: Have you tried to give it some gas when cranking? However, there is some chance it could be your cam sensor.

 

Yeah I tried to give it has but it was just cranking over. It didn't wanna start. After that, I plugged it back in and it started right up. The rusty part of the MAF were split already. I'm guessing they just broke off if I remember. I've been trying to sell the car but nobody wants to buy it since it stalls out.

 

Check IACV pins for resistance.
Center pin top to right and left, center pin bottom to right and left. All 4 tests should have resistance.

 

Could it be this?

 

I revved the car and it's supposed to open a little valve when it passed 3k rpm but it didn't open so I think it's that solenoid that's making the car stall then.

 

The VIAS is run off of vacuum and has several vacuum lines running to it. A vacuum leak in those lines could easily cause stalling but allow the car to run alright once it gets going. It would also cause the VIAS not to work. The VIAS failing on it's own won't cause stalling.

The VIAS system lives on the passenger side of the intake manifold and under the engine cover. It includes a canister, a solenoid and lines that go to the side of the intake. Check all those vacuum lines for leaks.

If you don't find any vacuum leaks, I'd also consider replacing the MAF since if it's old enough to be physically breaking down and rusting. A bad MAF can cause all sorts of different problems. It's not an on or off type part. It can cause problems but still allow the car to start and run.

 

Thanks, I really appreciate it.

 

No problem,

Now that I'm thinking about it more, a vacuum leak will cause the VIAS not to work but it shouldn't cause it to throw that code. That code is for the solenoid either being unplugged or bad. You can remove all the vacuum lines from the solenoid and it still won't throw a code as long as it's plugged in. I'd say that the solenoid is bad and you're VIAS isn't working. This will cause you to loose power in the higher RPMs but it wont cause your stalling.

If you're interested, I have a working MAF and a working solenoid here. You can have both of them for $40 shipped. They're used but they work. Send me a PM if you want them. I'm not guaranteeing your MAF is bad but you can test the theory with a known good one.

 

Maf for sure
