94 civic ex d16z6

Recently did an engine swap stock for stock engine (old engine crank broke off with pulley still attached) also replaced clutch (clutch kit). Ran great for a week with no issues. Saturday did an ac recharge ran fine with AC, Sunday ran fine with ac. Monday coming to a stop light engine idle was low and felt rough this is at operating temp. Has not died on me yet but very close. I turn off lights and AC and same thing. Also does it in neutral. Checked hoses and I cant hear or see and leaks. NO check engine lights. I have small clutch master cylinder leak but she shifts fine plus it does it in neutral. Other changes are environment, it has been humid and cloudy 76 degrees, It has normally been 90s.

These items were replace fairly recently and ran great with old engine.
new spark plugs and wires
new dizzy
pcv valve is new
new main relay
