My truck has been running like cr*p lately
runs ok but if i drive aggressive bye hitting
the gas hard its starts cutting in and out why
new fuel filter,cap&rotor, wires, pick-up coil,coil,
control-modulator,fuel lines and has 296,500 miles
on it what would cause this
note it acts like it is not getting fuel.but if i hold the brake and press the gas a little and a few min
it starts to run fine or unless u stab the gas a little

your fuel pump could be getting weak, or maybe trash or water in the fuel system.

Not everything will show up on TBI's as far as codes.Have you checked the timing?Also make sure you dont have any air in your cooling system that would mess with the coolant sensor,I would purge it to make sure there is none.Air in the cooling system can mess with the sensor and cause all kinds of problems on tbi's. Once you know your fuel pressure and fuel pump are ok I would try this.It could be a lot of things but I would start with the small ones first.Im assuming its been taken care of and maintenenced.You didnt mention if you changed the plugs yet.

check your egr vacuum censor. May need replaced. But stepping hard on the gas with a truck that has almost 300k miles on it is not really a good idea.
