Hesitation , skipping,engine cuts out when accelerating
I have a 1993 chevy lumina,3.1 ltr v6
when the engine is cold it runs fine. when it warms up the engine skips and pops during acceleration , it acts like the timing is off. but only when the engine is warmed up. also it idles fine all the time
Im having the same issue I believe. I have a 94\' Chevy 1500 and when i accelerate it will jerk like the gas has cut out but it wont stall. It just jerks and slows me down. It only seems to do it when going up a hill. I feel like it could be the fuel pump or possibly some intake gaskets?

Does it seem like when the engine is cold it runs ok, then when it reaches operating temp. it starts acting up? (poor acceleration, stalling) When I had that problem w/ my 93 K1500, it ended up being my oxygen sensor. (causing too rich of a mixture in the throttle body)
Hope this helps, Good luck
