when i rev at a stand still say just kinda showing off and the rpms get to high they will come down then jump up to about 2k then go back down. Just wondering why its doin that. 2006 2.0 ss/sc
Thanks!!

 

It's possibly ur throttle body needs a cleanin. Other than that, I can't see why it'd do that. I've done the "show off rev" and it takes forever to come down, but doesn't jump back up after it does.

 

thats what i was thinkin, but wasnt sure. any super easy way of cleaning the throttle body?

 

its throttle body pretty sure

 

Take it off, use some carburetor cleaner, make sure its all dry.....you should be good after that......keep a small wire brush close if you have corrosion on it

 

And be really careful with it when you take it out. You don't wanna do anything to damage the butterfly valve or it's mechanism cuz then the jumping rev's won't be ur only problem

 

i hear ya on that one! thanks! will have to put that on the list for things to do in the morning!

 

yeah my friend said he had same problem, he cleaned the throttle body with stp throttlbody and carb cleaner, its the oil commin out of the vent on valve cover,gummin it up...recomend oil catch can,i need to clean mine too

 

its not the throttle body, its the emissions control unit, its trying to burn all that gas you just threw into the cylinder, so there is not all that unburnt emissions out the tailpipe

 

Yup.

Completely normal.

 

ok, if its normal then its cool... just dont want something to get worse and then have even more problems later.
THanks!!!

 

Mine does the same thing...

 

Same Here

 

try re-intsalling your landscaping rock mod....i'll bet ur rpm's quit jumpin around i couldn't help myself

 

idk exactly how normal that is my car never does this. i just fixed a car that was doing this by cleaning the throttle body and then the MAF sensor

 

I don't know why you would rev anyways.

 

100% normal.

 

because people loooove being ricey

 

It is 100% normal for these cars to do this just as an fyi.

 

As said many times before, its normal
