Nissan Maxima QX V6 biggest problem

[Soldier]

I have problem with my Nisan Maxima QX V6 1998.

The problem is that engine stops working then I put shift lever on R position also sometimes it stops then I drive on D slowly (without acceleration) in the traffic jams.I visited several garages but nobody can find any problem. Computer doesn’t show any mistakes, so I am in deep shat.

When I bought this car it has problem with transmission, so I had to change it. Maybe it could be connected?

Also sometimes it wont start in the morning.

I have changed a camshaft sensor, all the plugs and checked ignition coils but nothing helped.

Thank you for any help in advance.

I would check the Idle Air Control valve.

[Soldier]

Could you explain me a little bit more about it.

As far as I know, (computer shows) when engine stops simultaneously it gets more gas than usually, it means that with gas everything ok. And something should be wrong with air or electricity.

When the Idle Air Control valve gets dirty or malfunctions, the engine will get too little air, causing it to stall out.

i have no idea what wrong.. but can you take a picture of your air intake system... i cant find the IAT sensor and i wanted to see what yours looked like.. thnaks..........

[Soldier]

Unfortunately I don’t have an air intake manual, but I can take few pictures of this system tomorrow. IAT sensor – is it Intake Air Temperature sensor? could you write in fool words pleas.

no problem, yes that is correct the air intake temperature sensor, anyways i have seen many pictures but none of them look like mine.. if you wanna see what mine looks like... let me no and i will post it here for you.... thanks for the time man....

[jltibbs]

the IACV is mounted at the intake manifold, the IAT is along the air intake tube. it has 2 screws holding it in.

[nyvenom30]

yeah i no but for some reason my car is different thats why i need to see another 98 maxima se and see if its the same other wise it looks like my car doesnt have one..........

[Soldier]

I cleared this valve, but unfortunately nothing change, then I changed from other Maxima 3.0 l. but everything is the same. But there are more tubes and wires connected with this valve. Maybe something guides this valve??????

And I took some pictures but I cant place any pictures in this webpage maybe somebody can help me with this.
