85 Civic Wagon - Idle and Power Issue
 

Engine: EW1

So far, I've checked to see if there's water in the oil from a blown head gasket: Negative. Vacuum lines: Spaghetti. Spark plugs: Changed. Timing: Checked.

The car will idle on first start up, and stay revved to 2000, but as soon as it gets warm and the choke turns off, the car completely dies, refuses to idle, and has no power after warm.

I'm tempted to just pull it and drop the D16A1 in it, (it's the 4wd model). What would you guys recommend to check next before I make the plunge into an engine swap? (Which I've kinda started because I am tired of fighting with this engine already)
