New 6 cyl in 97 wrangler. Idles high, when put in gear it wants to stall

What is your question?

I put a used engine into a 97 wrangler, 6 cyl. Timed distributor, runs a high idle now and when I put it into 1st gear it wants to stall. I am at a loss on what else to look at. Plugs are good, fuel is getting to the fuel rack.

What makes this problem better or worse?

Nothing

How long has your 1997 Jeep Wrangler had this problem?
