A cool front went thru my area last night. When I started my 93 S-10 with 2.8 this morning it was idling way too fast. I figured once it warmed up things would settle down but after driving 30 minutes to work it was still idling about 2500 rpm.

 

Any ideas what could be causing it? When I got to work I checked the linkage and nothing seems to be binding. Is there a sensor that may need replacing?

 

Thanks,

Beaux

A close inspection of all the vacuum lines last night revealed a crack in the PCV line.  I repaired it and this morning everything was fine.  Hopefully it'll stay that way.
