I have a 89 F-250 302 fuel inj with a stalling prob. (82000 miles) I can drive it on the freeway and it wont stall out, but when i go to slow down below 35 mph it acts like i shut the key off. The truck sometimes will start up right away, other times it takes up to five minutes. I can drive (stopping and going) 20+ miles at times without it stalling, But i will stall. I' had it in the shop and they checked it over, even drove it and it did not stall for them "dont think they drove it enough" HELP!!!!

Believe it or not I had the same problem with my F150. FIrst check your idle rpm, mine was a little low and it helped out the stall problem to adjust it higher (change the plugs also will help if it is oil fouled). Also check your battery connections, the starting problem (5 min) might be corrosion at the terminals or even the cable (l cut off the bad section of cable near the battery connector and installed a clamp on connector a $4 part for both pos+ and neg- terminals at the auto stores). If not that that ECM module is probably it, or a fuel pump problem (also similar conditions that a starved engine will stall out and not start esp. if the pump is working intermittently). Good Luck!! :wacko:
