'95 Nissan Pathfinder stalls when letting off gas Sign In

I have a '95 Nissan Pathfinder (6 cyl; 4 wheel drive) -- My car stalls whenever I let off the gas or step on the break. If I'm stopped at a light it sometimes idles and vibrates at the zero RPM--then proceeds to stall. It also produces a funny smell when this happens. I took it to the shop and it was deemed that nothing was wrong with it. I've done the fuel treatments and replaced the gas cap and neither has worked--any ideas as to what may be wrong?

Note: this has been going on for a few weeks now and it only happens when the car is warm. The O2 sensor has already been replaced and we have reset the computer--no dice.

Sounds like you could have an EGR valve sticking open at idle. This could be due to chunks of carbon getting caught in the pintle, a defective EGR valve or a defective vacuum control solenoid.

I would say the next time it happens at a place where you can work on it, shut it off and immediately remove the EGR valve and inspect it to see if it's stuck open or not.

What do I do if it isn't? If I take it out now (I haven't driven the vehicle since last night but it was all shades of awful last night) would I be able to tell if that was the issue? Or should I just drive it around for a little bit and then take a look? Maybe even just clean it out to see if that helps without driving and experiencing the issue?

If it still keeps stalling and that isn't the case what should I look for?

The problem needs to be present when you shut it off for you to find anything.
