1996 Dodge Ram V8 Automatic 107000 miles

I got a 96 ram 1500 gas with 107000 and the truck won't idle. I start it and it idles but once I get down the street and I slow down to take a turn or stop it will die. I undid the y pipe to be sure the cat wasn't plugged but it still does it. I'm thinking it's a sensor or the pump. I disconected the hard line coming out of the tand and switched the key off and on and it shot put fuel like a champ. I need help

Have you checked for vacuum leaks? Has the check engine light come on?

Let me know.

I haven't checked vacume line yet. No check engine light except when I took the y pipe off to check if the cat was plugged but that jus the o2 sensors. So jus check vacume lines goin to the throtlle body? I've been lookin around the web and alot of the questions r answered by cleaning the throttle body.

A good cleaning can help. However, check for leaks too and make sure the EGR isn't carboned to a point it doesn't work.

Good question but we'll figure it out. I miss my 78 power wagon step side with a 400. Nothing went wrong with that thing.

Would this proble have anyting to do with my battery or alarm. I was wheelin Sunday and at the end of the day I went to start my truck and it jus clicked and the alarm went off and it wouldn't let m deactivate it with my keypad so I disconected the battery and pu it back on and it started but the only differnt thing it did this time was when the Alarm went off it got lower and lower in tone til it completely stopped. So I did th battery thing again and started my truck. The next morning u went to start my truck an that's where I'm at now

Are you able to replace the hose? Also, chances are it goes to the heater panel to adjust the vent doors. Try to replace it if you can and continue looking for others that are bad. Also, have you checked the EGR?

I will try and replace it alltogether but of not I'll get some of that stuff u heat up so it seals. How do u tell of the egr I bad? Also, when I undid the exhaust and ran it straight headers to see of the cat was plugged. Will it run bad now cuz the o2 sensors arnt active in the exhaust system?

Remove the EGR and check for carbon build up. Clean it and the intake where it bolts on. After that, there is a valve in the EGR that is vacuum operated. Make sure it is opening and closing with vacuum.

It will run without the o2 sensors, but not too good.
