Revs pause when taking off 97 gtx

[Carguy89]

Every once in a while, when I leave the no-wake zone, I'll hit the gas (say 1/2 throttle-ish) and the revs will go to like 4000-4200 rpm, and pause, regardless of how hard the throttle is depressed. If I lower the pressure, then get on the throttle again, it'll be fine.

Ideas? It's got about 50 hours on the rebuilt motor, and only about 3 this season on the new plugs.

clean the raves.

Is that recommended to do right away, or can it wait a little bit?

I.E. - Will it hurt anything?

cant hurt, only helps the motor to breathe out the spent gases. Need to clean them every, depending on what type oil your using, between 20-50hrs of use. I cleaned mine one time, only for them to clog up, about 5hrs after use, guess i missed some carbon in its housing area.

Ok, that's what I figured. Thanks. And I only run the XPS oil.

I feel like an idiot, but don't see a sticky or anything on it - how do you clean the raves?

Brake Cleaner

Use any kind of brake cleaner, a scotchbrite and wirebrush. I have the luxury of working in a machine shop with all types of cleaning equipment and polishing equip.
