Hey all, I had an oil change just a few days ago, and right afterwards, my idle seemed to jump up. I was idling before around 750rpm or so, but now, it stays at 1500rpm, and last night it even went up to 1800. It was perfectly fine before the change, but right afterwards, the idle became high. I did go from a 20W50 oil to a 10W30 oil, but I don't think that this should be an issue.

Other than being high, the idle is relatively smooth, any ideas on what could be causing it and how to fix it?

 

Did you do the oil change...or did a shop do it? If the latter, go back and ask'em if they touched anything other than the filter, the filler, or the drainage ****...heh

Edit: This is jarhed from [m]

 

my money is on a vacuum leak, but i can't seem to locate it :\

 

Yeah, mine and colinshark's as well =\

As I asked though, did you do it (check everywhere you touched), or did some mech's shop do it (ask them to check everywhere they touched)?
