Engine stalls out?

Same issue here what did your problem end up being? I have changed the TPS sensor, injectors, fuel regulator, plugs, wires, cap, rotor, coil, runs/idles strong but then put into gear and it stalls out. Any ideas would be great thanks. 1990 Chevy Silverado 350 V8 5.0L

Idals fine till put in gear then dies

Chevrolet Silverado 1500 will die while idling and when put into gear. What could be causing this to happen? Replaced distributor and is in time.

Problem

Ill start the truck to let it warm up and at times it will stall but it will start right back up. Main problem is I can be driving just fine and then the truck starts jumping example like someone learning to drive a manual shift like your going to get whiplash (LOL).
Then if you push the gas pedal all the way to the floor it doesnt pick up it will keep on jerking you or starts to pop like backfire. I know it is ticking me off, My mechanic has said its either the fire its not getting or the fuel pump. But what has him confused is that the truck always starts back up.

I sure as heck someone here know what it is.

Thanks

Check engine light come on sometimes not a steady light

The fuel pressure was checked it is fine, the dino didnt show anything wrong. But the fella told me its nothing to do with the fuel but it is in the ignition.

I just had new plugs and wires, distrib cap and rotor put on the truck.

Engine starts then stalls, after about approximately 15 min it finally keeps running. This happens in the morning
when I go to start about 8 hours later it starts up fine. Truck is park in the garage over night and parked outside during the day. Any Ideas? Thanks

I recently got a truck when I got it it had open headers on it I started it and drove it home no problum the headers were rusted out so I put new headers on and ran strait pipes ever sience then the truck will start and run fine in park but as soon as you put it in gear and have a load on the moter it stumbles and stalles right out iv replaced the o2 sensor and check all vacume line for leaks and couldn find anything what do you think it is?

Ive checked the map, maf, and erg valve and it still does it when you first start it up you can hear a loud air sound but cant find the leak could it be the tbi gasket

Ok so when the truck is in park it it runs fine perfect no misfire nothing you can rev the motor in park and tell that it is runinig perfect you can see the gas that is comming out of the fuel injector flow faster when you rev the moter so I dont think it is fuel pump or pressur problums iv drained my gas tank and put fresh gas in it new fuel filter I chance the iac valve iv tested all wires and got all proper voltage to map sensor. Emc sencor. Tbi sensor.O2sensor. And egr silinoid and checked the egr valve changed all vacum lines cleaned injectors. But still when you put the truck in gear it will idil fine but as soon as you step on the gas it stallswhe in gear not in prk its fine engin does not hesitate all new plug and plug wires truck never did this untill I put new headers and strait pipes on. When you disconect the the vacum line from the map sensor the truck runs ruff so im sure that that sensor is working but how to I check the egr silinoid. And my truck doesnt have a maf sensor. My oil pressur is extremly low when motor is warm why is that? Could that be the cuase? Plz help this is coasting way mor money then the truck is worth

1989 k2500 5.7l. Engine fires but shuts off when warm or if it stays running when I give it gas. I have thrown part after part after it but no change everything I can think of a junkyard TBI, a new computer, new EGR new, EGR valve, new plugs, new wires, timing set. Going to check fuel pressure next, but I don't know how that would make it act like it is. It feels like it's running fuel rich so even when. I play with the throttle and keeps it running for a short bit 1 minute max. Any help or advice would be great.
