Re: 1987 ram 250 p/u stalling
i'm thinking if he has a 4 barrel, which means a carb, he should have between 5-7 psi. also, if it a carb, check the fuel bowls. i had a duster do the same thing and found out that the fuel bowls were filling up with rust particles that were not being filtered out like they should be. i replaced the filter too and that didn't help. eventually, i had to drop the tank, totally clean it out, clean out the fuel lines (from all the rust goin thru), and rebuild/clean the carb out. once that was done, it was goood to go.
also, like the other guy said..timing. i had a d150 that would do kinda the same thing (just not real predictable) but i found the timing chain was toast. replaced it and all was much better in the world.
