I got a 1997 dodge ram 1500 5.9 and it has a stalling problem. When you come down to a stop the truck like to drop idle down to 500rpms and lower and try to die and it sounds like it has cams. She also likes to stall at 1800rpms and them fall downa to where the rpms should be. Now I have already change the IAC senor and the TPS senor and cleaned the throttle body. What do u guys think?

 

Did you reset the computer ? And have your battery tested.

 

I rest the computer and the battery is fine. I think the map senor is messed up?

 

Where did you buy the sensors? If you got cheap ones from Advance, Autozone, etc... Chances are they are junk. And how do you know the battery is good? Not just because it starts fine .

 

The senors are from Dodge and the battery is brand new just put one in it bigger than normal.

 

injectors?

 

It doesnt throw and check engine lights. It does it when it wants.

 

I had a similar problem, but then I remembered I had disconnected the coil wire but didn't snap the coil plug back in place. Make sure all your connections are tight. also, inspect your vacuum lines for any cracked or chapped lines.

 

Wondering if it happens when your on the brakes? could be a vaccum leak in the brake booster.

 

Yea it happens when you are on ur brakes and it will do it when the truck is just sitting in the driveway.
