'00 4cyl EX 5-speed 125k mi

This started all of the sudden like turning on a switch. Under heavy throttle at low revs the engine will buck and stumble. It runs fine with a light foot or at high revs. Replaced plugs, distributor cap and wires, no different. Mechanic friend says dirty injectors and to use Tetron injector cleaner. Two tanks later, still doing it. Am I not patient enough for injectors to clean out?
Another person said it may be electrical like coil. (Really?) I thought fuel filter, but couldn't find it and same mechanic friend says it's in gas tank and not worth the trouble to change.
It's one of those things that I could replace part after part trying to figure out and drive myself crazy and end up nickle and diming myself to death.
Any suggestions would be appreciated.
