TeeJay3800 Posted November 11, 2003 Report Posted November 11, 2003 What is the ideal idle speed for the LH0 3.1? On a cold morning (say 25ºF), immediately after starting the motor settles down to about a 1200 rpm idle and after about 2 min is down to 900-1000 rpm. When the motor is fully warmed up after 1/2 hour of driving it idles around 600-700. Is this the proper idle speed for this motor? BTW, I already followed the idle relearn procedure on 60degreeV6.com. Quote

Baddflash Posted November 17, 2003 Report Posted November 17, 2003 Sounds fine to me. Mines the same. Quote
mfewtrail Posted November 17, 2003 Report Posted November 17, 2003 mine is about the same....when my IAC went bad a while back it would shoot to ~2000 or maybe a bit more on cold starts(cold days..it was during the winter last year it went bad)..I drove it like that for 2 days, needless to say I worked in a highly populated area and tons of people wondered why I was giving it so much gas at start up...w/ the exhaust = loud as hell Quote
91cutty Posted November 17, 2003 Report Posted November 17, 2003 shouldn't it drop down to 650 rpm sooner than 1/2 hour? I know mine did after about 10 minutes driving. Quote
PaPaPooh Posted November 17, 2003 Report Posted November 17, 2003 i looked at this in alldata at school cold start up 1200 to 1300 regular warm up time and after warm up in P or N 800 to 900 in gear it is 600-700 Quote
Intlcutlass Posted November 17, 2003 Report Posted November 17, 2003 Mine is also the exact same. Quote
