This could the symptom of so many things; bad plug or wire, vacuum issue, coil, etc etc. Best thing to do is to go to Autozone and have them read your fault codes for free to narrow it down considerably. You can also buy a code reader these days cheap. Buy an ELM 327 blue tooth module from Amazon from Yongtech or similar for $10-$20, and then download a free mobile blue tooth app on your smartphone or pad such as "Torque" and do it yourself now and in the future, real easy. Also, what year and model car do you have?

Sounds like your fuel pump starting to die. It is not getting enough gas under heavy acceleration which is 100% fuel pump slowly dying. At start up it might not be building up enough fuel pressure to feed the system but the shot of ether and engine cranking helps pressure the system just enough for the fuel pump to trickle the gas and run the engine at low rpms.

1997 geo prizm won't stay running sputters and dies upon acceleration


If the check engine light is on you should have the computer scanned for trouble codes. The codes will direct you or a mechanic on where to look for the problem.
Sometimes the problem is low fuel pressure or a dirty fuel filter.

you have an engine miss, any time the check engine light starts flashing the engine is missing, should be an easy fix sounds like either a bad spark plug or a bad plug wire if you have the codes checked there should be a code telling you what cylinder is missing, but if i were you i would tune up the engine all new plugs and wires and filters......GOOD LUCK
