RPM At Start Up

eNCore · 01-19-2012, 07:55 PM

The RPM revs to 2k on start up (I know this is normal.) and when it gets to around 1k it revs up to around 1.5k (normal?), then it's kind of not steady till the car warms a bit (normal?). I know older models have Idle Control Valve issue, but I thought they fixed it or this is all normal?

Its normal. Has something to do with how the car heats up the cats at startup.

This is not normal.

It should never hit 2000 on startup.

It should look like this

Doesn't sound normal to me. Mine revs to about 11 to 12 hundred rpm immediately after cold startup. Within a minute or two it settles at about 8 to 9 hundred and stays there during idle.

That video is the normal startup. Well eveything but the butchered pronunciation of akrapovic

2K is up there though. I would contact elp_jc. He had some issues with idling and was taking a look at the control unit I believe. I don't know how he made out with it.

Haha, I've given up on that word a long time ago. I have my own rendition now
