does anyone have this problem? i have a 1.8 SL and when i start the engine in morning w/ a/c on, once the engine started, the rpm boost up a little bit (100 rpm) for 1 second, and then it drops to down. and it only happens in the morning (the engine is cold). But then it didn't happen again as I start the engine after it's already warmed up.

Re: rpm boost up for 1 sec when a/c is on before starting up the engine in morni

It is normal as a load is being put on the engine.
