I've posted this before, I have a '95 Dodge ram 1500 4x4 with a 318. Previously I posted a problem where I would come to a stop and the truck would die on me. I was told to replace the IAC sensor and clean out the intake real good. So far the TPS, IAC, Mass Air Flow, plugs have been changed. The truck acts better, but still dies randomly when it comes to a stop (not nearly as often). Does anyone have any suggestions on what I should look at replacing next? Could it be a O2 sensor screwup, any ideas would be great

Is it kind of choking down or is it just dying instanly?
I wonder if it could be an injector problem. what about when it is running? Any hesitations? It is hard to say if it is ignition or gas troubles. And too it could be a vacuum leak somewhere. You might need to check all your vacuum lines.

I ran 89 octane through it with some injector cleaner (through tank). It died when I pulled out of the gas station but didn't have any other problems.

I don't know anything about how vacuums work. I do know that another odd problem is when I accerlate the amount of air being pushed out of the air vents decreases alot.

Someone suggested the EGR valve, another suggested Crankshirt sensor, and another one said the fuel pump is dying....

Alas

i would say the next check should be your egr valve. it's highly unlikely that all your fuel injectors would suddenly clog, and if even one or two did you would notice it at higher rpm as rough running or missfiring. same with the fuel pump, you would notice it more at higher rpm cause it wouldn't be able to supply the required amount of gas. could be a vacuum leak somewhere and if your egr valve is bad, that's exactly what's happening. valve is leaking by or stuck so you are losing manifold vacuum. a hanes manual will give you lots of checks you can do to see if the valve is good or not before you spend the bucks to replace it.

Broke down and paid the $90 for a new EGR valve. Installed it in 30 minutes and bam - runs great. I'd recommend taking off the air box if anyone tries this...makes it alot easier

iac, main item causing it to shut off when gas pedal is released

Try cleaning your throttle plates.Had the same problem,worked for me.
Sounds funny but true.(Clean, not scrape)Hope this helps.
