'88 YJ sputtering question
I have a '88 YJ with the 4.2 liter inline 6. The engine does have
quite a few miles on it but seems to do alright. The question I have
is why would it hesitate and sputter at low rpm's when I load the
engine? For example, when starting out from a stop? The Carter BBD I
rebuilt not long ago and now I just put a Motorcraft 2100 on and I
still have the same problem? Also, with both carburetors I can't seem
to get the idle rpms down from about 1000. What should I look at? I
have adjusted the idle screws and the mixture screws. In fact, the
idle screw isn't even touching now to get it down to 1000. Any help
would be appreciated.

Re: '88 YJ sputtering question
Have you checked everywhere for air leaks or a missing/cracked/broken hose?
