Re: 1989 dodge Ramcharger stalls
I assume you have power brakes and I gather that it idles properly at times, but dies when the brakes are applied. This sound like a leaking power brake assist vacuum line or diaphram. You can verify this by locating the big vacuum hose connecting the intake manifold to the assist diaphram. This will be about an inch in diameter connected to the round item behind the brake master cylinder next to the firewall.
Disconnect the line at the intake manifold end, and plug the vacuum port on the manifold with a tapered rubber stopper or cap.
Being aware that you now do NOT have power assist to the brakes (requiring CONSIDERABLY more pedal pressure to stop!!!), see if the problem goes away. If it does, you have narrowed it down to the assist diaphram or the hose. If it still persists, it is an engine tuning/control issue, not related to brakes.
Do determine whether it is the vacuum hose or the cannister, remove the previously installed cap/plug, reinstall the hose to the intake manifold, disconnect it from the diaphram and plug/cap the hose at that end. Repeat step three... if the problem returns, the hose is leaking and should be replaced... If the problem still goes away, the Power Brake Assist Diaphram Cannister is leaking excessively and should be replaced.
***ALSO*** Any other vacuum lines leaking can lower the manifold vacuum to a threshold level where the load of power brake assist actuation crosses the line for adequate vacuum to idle*** So check all vacuum lines underhood, looking for a pronounced hissing at vacuum leaks. A manifold vacuum gauge is a relatively inexpensive diagnostic tool that could also be useful.

You have an intake vacuum leak. The vacuum is sucking in water and causing the truck to run rough. It may get better when the truck is hot because this sometimes causes the plastic or gaskets to swell closing up the leak. To confirm ... when it's cold you can start the truck and spray some brake cleaner or quick start around the sides of the intake and you will see the engine will rev up a little.
Hope this helps.
I have a 1988 dodge ram charger with a 318 motor with throttle body. It runs really good when I start it up and drive it for about a half of an hour. But after that when I step on the throttle a little bit, it hesitates. If I let off a little bit, it will go or if I really step on it, it will go also, but if I just hold it there, it really hesitates If I stop, the idle jumps up and down so much it causes itself to stall. It seems to only do this at low RPM's. If the RPM's are higher it's fine
i had the same experience but what i have come to find out on the 89 tbi they usually run best when timed by ear or feel if it idles good and runs fine drive it just at smog time tune it wit a light they get us out here in cali if its off at smog only stations
