Re: o2

thanks for the info, thats around the temp i had on my scanner. i thought it was too low. my truck idles fine till it switches from open to closed then it stumbles looking for idle till the truck warms up. i've replaced every sensor i have found on the search, adjusted fuel press, adj ias, installed new ecm. and rebuilt the motor to still have the same idling issues as before. they don't make a strong enough DRUG for this headache in the garage.... any other ideas to look for would be greatly appreciated thanks danny
