high warm idle... 200 85Ti

posted by  someone claiming to be erik on  Mon Sep 17 16:19 CST 2001 [RELATED]

hi,

my warm idle (1700-1900 rpm) is significantly higher than my cold idle (950). it didn't happen overnight, but more like over the span of a month and it seems to be getting higher with time. everything with the cis system checks out per bentley (ie cis motor, coolant temp sensor, ecu, idle switch, base idle, etc). i've also cleaned out the throttle body and replaced the gasket. i'm totally stumped. is it possible that a failing o2 sensor could somehow be telling the ecu that the car isn't warmed up, hence giving me a high warm idle? what about bad injector seals (though they were replaced only 25k miles ago so i doubt them)? any input gladly appreciated.

erik
