1995 Nissan Maxima stalling

I was hoping someone could give me a suggestion as what to do for a 1995 Nissan Maxima Gle 6 cyl, 24 valve that seems to stall out.

I had changed the fuel filter, injector cleaner and air filter


It idles fine, starts fine but when it is in drive and the peddle is pressed it stalls out


Especially when on a hill where stress is on the engine.

I had a very similar problem with my 85' Maxima. I had just done a tune-up on it when my wife almost got in an accident when she stepped on the gas to get out of a jam and as soon as it about 3000 rpm, it just dropped off stalling. I spent hundreds of dollars having specialist try to fix it. I of course told them all not to check the things I just replaced, and they faithfully did not check them. Finally I started to do my own troubleshooting. I found that the brand new Fram fuel filter I installed was faulty. It was plugged somehow, I could not even blow through it. I have always been told that you should be able to blow through a fuel filter. Al's Auto Supply, were I had bought the filter, paid me for all my expenses and replaced the filter. This fixed the problem. The fuel system is most likely to be the problem.

Hope this helps.

thank you for your reply,
I too had tried that. flues system seems ok.
what do you know about the air intake controler?
It is the 2 boxes attached to the air filter that feed the engine?
