Name this problem ?

Starts great, Idles fine, But when you step on the gas to rev it, it Stumbles, Skips, and Loses power.
Plugs and wires have been changed. What would be some things to check or Clean?

Many hypotesas from low fuel pressure to clogged cat.

As I've understood, there are no codes....

Bad TPS - rev up with delay.... That is all.

Bad MAF - CE Light and code, wont rev up well.

Sounds to me like something is causing fuel restriction. Clogged Fuel filter, bad fuel pump, low fuel line pressure or leaking fuel pressure regulator, gummed fuel injectors. Gunged MAF sensor.

What is your MPG on highway?
