b2500 stalling
 

Hello , I have a 1999 b2500 and keeps stalling driving me crazy. Iv"e searched the web trying to figure it out. I have been replacing parts left and right with no change. I have read that it might be the sensor that hooks up to the exhaust manifold so I replaced it, and the egr valve still the same. new plugs and wire's ,timing belt ,crank sensor . I have looked for vacuum leak's haven't found any I have put seafoam through the system . Next thing that I'm looking to replace is the idle air control and the throttle position sensor which will set me back another $100. before I spend the money I figured I would ask if someone has had the same problem . Thanks for any input:confused:

What are the symptoms?

it takes a while of cranking to start once started if you give it gas and let off it stalls out as soon as you take your foot off the gas. Then crank it for another 5 min. or so same thing. While your cranking the engine looks like it going to jump out of the compartment shacking all over. I replaced the timing belt before cause it snapped, I thought it might have jumped a tooth so I took it apart again and every thing still lined up. I am at the point of taking a sledge hammer to it.very frustrating

Have you checked the mounts and harmonic balancer? Maybe check your grounds as well, I've had a bad ground and it had a hard time starting when it even realized it had a battery. It stalled out if i didn't keep tapping the gas pedal.
