hesitation/stumble 95 tahoe

[ERIC95TAHOE]

i have a 95 Tahoe with the 350. when its cold if you tap the gas it will kind of stumble or hesitate a bit. while its warming up it will sometimes randomly hesitate when you go to take off. i wouldn't really say its a miss though. then when it warms up fully it will have a little shake to it. i just changed the plugs and wires on it about 4 months ago. any ideas whats going on here?

vac leak?

vac leak?

i thought that too but i looked for that. found nothing. i changed the coolant temp sensor just now and that didnt do anything.

Mine used to hesitate when I first started it but after I changed the wires, plugs, and dizzy it was all cleared up. It used to have a noticable shake to it at idle also but that it mostly cleaned up. Is it normal for these trucks to have a little shake to them at idle?

one thing i didnt change was the cap and rotor. i may try that im sure it needs it.

i did notice it seems to shake at idle only when its warm outside. my hesitation/ stumble is mainly if a snap the throttle kind of quickly. when its cold and sometimes when its warm. what are my injectors suppose to look like when they are spraying? i looked down in there with a timing light and they seem to throw fuel all over the walls both exactly the same though.

mine was doing something similar and i put it on computer and it says it is the crankshaft positioning sensor

its a bit annoying but not $235 annoying lol. im going to put a new cap, rotor and coil in. it seems to be worse when its wet out its raining right now and i noticed it every single time i took off

Possibly your in-line fuel filter...
