Is a Throttle Body Cleaning Worth it for an L99?
For years my idle has run rough. Inside I can't tell but outside it sounds like it almost wants to stall, then revs back up again. It's stock but it almost reminds me of a cammed Shelby I had, but of course less extreme. Is this normal?
The dealers always try to get me to do a throttle body/injector cleaning. Isn't that a ripoff on an L99, or should I do it? |

How many miles are on it? Do you have a catch can? Ported throttle body? Maybe just use a can of sea foam

It’s normal. Mines done the same since new. I clean my throttle body every time I go WOT
