Hello Bob and Ken and thanks in advance for you assistance. I have a 1997 2.4L Nissan Altima GXE. The problem is when I first start the engine the car drives good however after about 20 min. of driving I lose power and the car stalls out. During this time I can not exceed 3000 rpms or the car will stall and begin to sputter and vibrate. It also only will increase speed if I continue to gradually add gas and not exceed the RPMs. I have checked the lines and all hoses. I also checked the fuses. I tried to get a reading from the car but the code reader could not get anything. The service soon light is still on also. This problem just began about 4 days ago. If you could help me please do.

Have the fuel system check that clears out-we'll go to other areas

I have changed the fuel filter and checked the entire lines. I also had the injectors cleaned. I am wondering could it be the coils or the module that is giving me the problem since the vehicle starts acting this way when it runs for a while?

When it dies out-immediately check for spark and fuel one of this is gonna be missing in action.

Comeback and tell me what's missing we'll go from there.

Remove a plug wire stick a screwdriver in it and ground it to the engine or good ground point crank it over it should be producing spark and comeback

I did notice that when it died out it sounded as if it was not getting enough fuel

Was it running fine but quit suddenly? The most likely causes here would be a failed fuel pump, ignition module or broken overhead cam timing belt.

Try cranking it over while someone be listening to the injectors, it suppose to be clicking/buzzing and comeback

I think I have found the problem. I started the vehicle up and everything went fine until i touched the mass air flow sensor. When i bumped into it the engine stalled again and cut off. So I started it up again and pushed down on the sensor and sure enough the vehicle stalled again and cut off. Have you ever heard of this happening before?

Open it up and investigate what's happening in there check the flaps/ pins and test it out by the book specs.bumping on it shouldn't do that-just imagine if you're going down a bumpy road-you think its suppose to do that and get back
