258 Stalling when cold
I,ve got an 88 YJ with the 258. It ran rough when I got it last Feb. but I made a lot of adjustments and it seemed to run well. Turns out it was just the onset of summer that made it run better. Now that its cold out again... it runs great when I rirst start it and the choke is on but when it gets partially warmed, it won't hold an idle and I have to keep giving it gas to stay running. Once its warmed up fully, it runs great again. I had the emissions stuff taken off but put it back on a month ago (it made no diff.) I have also already backed out the mixture screws a lot. It seemed to help a bit but I don't want to take them out much more. Also my mileage seems realy crappy, maybe 13mpg is this right. 4 more months of winter... it's driving my crazy. Any suggestions?
