Hi and welcome to JustAnswer, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.

Initially, determine the burn color of the old spark plugs.

Stiil, let's try check and review the basics. Proposed preliminary tries (if have not been done) would be to check, clean the throttle position sensor and the wires, pins/connectors related to it.
