Stalling after exiting highway... Help!!!

Lately my 95 3.3L Intrepid has been stalling out after a highway drive when I slow down to get off. The engine reaches 1200 revs and then starts to dip down rhythmically to about 500 or 600, then it stalls out completely. Any help would be appreciated in fixing this. I recharged my K&N air cleaner last week, so that's not the problem. This has been going on for a few months now on and off. It has relatively new spark plug wires (one of them was failing and the spark plug was misfiring so I replaced them all). Spark plugs are maybe 1 yr old. That is all I have played with so far. Any suggestions?

Thanks!

Fuel pressure? or lack of pressure,more accurately...Easy guess says fuel filter, but that involves the gas tank removal, I believe.
Or clogged/dirty throttle body? Can you check computer codes on a '95 at the odometer?

I'm thinking it's the fuel pump (which is in the gas tank I think)........the fuel pump went on my '88 Aries and the car liked to stall..........sounds totally like a fuel delivery problem, it's either the pump or the filter, my guess is the pump.

If you have problems getting it to start, reach a shovel or something under the gas tank as you're cranking and hit it (gonna need 2 people for this one)..........I did that with my Aries and it started, so I KNEW it was the pump.

Dirty TB or IAC or injectors?

Did you check for codes? How does the car run after you restart it?

how do I check for codes? Do I need a code checking module or something?

What I have been doing lately (since it doesn't happen everyday, only when traveling over 25 miles on the highway) is put it in neutral and start it while still moving, then switch to D and take off again. So it starts right back up without a hitch.

Starting it has never been a problem lately. It will start up every time. It just dies after sustaining highway revs for 30 minutes or so...

Thanks guys!

Could be your cam sensor. You check the codes by using the Key on/key off/key on etc etc method

My brother told me it could be the vacuum tubes. What do you guys think?

I got no codes too...

Thanks for the input

I had the exact same problem in my '95 Trep and my 89 Jeep. both times it was my fuel filter. There is no need to remove the tank though. The one I had to replace is on the underbody rail (middle of the car, right hand side if I remember correct). I isn't hard to change, just be careful not to break the quick connect clips holding it on.
Read a manual about de-pressurizing the fuel system or you might get some spillage. (depressurizing is easy to do as well).
One last thing, leave your battery disconnected for about half an hour, to reset the memory,or your car still might not run as well after changing it.
When you drive on the highway, the fuel pressure drops,and the demand is decreased, hence better gas milage on the highway. But when you get off the highway, and have more demand for fuel pressure, if the filter is restricted the car stalls. (that's how a mechanic explained it to me anyhow.)
Hope this helps, but I'm pretty sure that is your problem.
