2005 expy 5.4L 3v
This is a mechanical issue not a technical one.
Amigos the truck keeps stalling everytime I stop or slow down enough to a near stop, here's the symptoms in experiencing
1. It stutters when in low rpms. It drops to 400rpm when in idle while in drive, shakes then turns off if I don't drop it in neural and rev it
2. It stalled while I was in motion (foot off the throttle) at low rpms crawling in traffic on first gear
3. This just start happening an hour ago, never has it stalled on me before.
4. I noticed that when I'm accelerating while in 1st gear the engine bogs and feels like it isn't delivering power between 1000-3000rpms, it drives perfect in all other gears and pulls hard. (This has been happening for about a week now)
5. Took it for an alternator test @ autozone (just eliminating possible causes), battery failed (however while holding 12.4v & it's less than 4 months old 850cca/1050ca) but I understand a dead cell will cause it to fail... But a battery stalling the motor while it's running I don't think it's the actual cause here. alternator passed Pumping out a constant 14.36v
6. No clue if fuel pump is been replaced or still original (131,795 miles) but fuel filter is new & less than 1000 miles on it.
7. Spark plugs are new less than 500 mileson them, original coils and original fuel injectors, no CEL codes and none pending either
8. When it stalls, it restarts immediately, though twice when I restarted it.. it almost like skips a beat for a second before starting but still starts fine after.
9. It does have an exhaust leak (exhaust manifold) but been driving fine with it minus the hideous noise it makes.
10. I'm leaning heavily towards it being a fuel related problem (pump or sending unit)
Please any suggestions will help, cause when it's happening to you at the moment your mind doesn't think straight and I know I can figure this out if I was home but I'm 96 miles from home and the only thing in my mind is get this POS expedition home
