After talking it over with a few people, and after reading the replies, I am almost positive it is the thermotime switch. Once the engine reaches operating temp the fuel mixture smooths out and it runs perfectly again. I was almost about to remove the new CPR and slap on the old one, but I'm sure I'll be safe just replacing the thermotime switch. That and the radiator are the only cooling system parts that haven't been replaced. After I change the switch I'll post the results. Thanks for the suggestions once again. I might as well change the radiatior so that it is out of the way, since it will be the next to last origonal piece left. :-) Thanks, Joe OBrien 2524 & 16634 To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
