Hello there.
There are a number of possible causes for the acceleration problem based on the information you provided. Consider the following options:
1) Despite the replacement of the fuel pump, fuel distribution may be an issue. A blocked gasoline filter, a malfunctioning fuel pressure regulator, or a congested fuel line could all cause this. It is vital that the engine receives enough gasoline and that the pressure is correct.
Check the gasoline filter for obstructions and replace it if necessary. Using a fuel pressure gauge, test that the fuel pressure meets the manufacturer's specifications. If the fuel pressure is too low, the fuel pressure regulator or fuel pump may require additional investigation or replacement.
2) If you have difficulty accelerating when utilizing the gas pedal, the electronic throttle control system may be malfunctioning.
I suggest that you inspect the ETC system for any flaws. This may include utilizing a diagnostic scanner to obtain any recorded fault codes, evaluating the throttle body for carbon build-up or other blockages, and inspecting the ETC system wiring and connectors for damage or corrosion.
3) The fact that utilizing premium gasoline temporarily enhances acceleration indicates a potential problem with fuel quality or fuel system components.
Try a different brand or supply of regular gasoline from a reliable source to see if the problem persists.
We still recommend having the vehicle checked by a certified mechanic for real-time diagnosis. Once the part/s to be replaced is determined, click this link where your vehicle information has already been entered. Simply enter the part's name into the search field to get started.
We hope this helps. Have a nice day!

If the car calls for unleaded gas an you put in high premium gas it may have affected the computer it may need to be reset I had a different car that had the same problem then I couldn't drive it in drive had to be in drive 2 or 3 and it ended up being my transmission but I hope its not in your case good luck

I had a 95 GMC 2500 pickup with similar issues. I changed plugs, wires, fuel filter, fuel pump, and had battery and alternator tested. It ended up being a blocked catalytic converter. I cut it off and had pipe welded in place. It ran fine after that.
