usually a bad WUR will start fine when cold then run bad when warm unless someone has tweeked the WUR or mixture to make it run good hot, then it has bad cold starts.

since this started while you owned it and i assume you have not done anything to it, i would look for air leaks. even with a bad AAR you should be able to idle the engine up with your foot.
if you are having to add fuel by pushing down on the senor plate that really sounds like an air leak.
check the IC seals. look for cracked or broken vacuum hoses. check control pressures. if your return side of the WUR is clogged it can raise the cold CP and make it lean.
