[urq] Lack of power untill up to temp

[MikeDes156 at aol.com]

Here's what's been happening. Car (83 urq) starts fine as always, but sounds 
a little like it's running on four cylinders for a few seconds, then it 
straightens out. (Maybe one of the injectors lets fuel enter the cylinder while it's 
sitting.) The car will run fine untill I floor it, and then it seems to 
stumble (back to running like it's on four cylinders) with a change in exhaust 
sound and power. Seems to happen around 12psi of boost. RPM dosen't seem to be the 
same when it happens. But once I've driven the car for 10-15min, it runs fine 
again. I can even let the car sit for an hour or so and it still runs like it 
should. The last thing I did on the car was replace the igloo with a later 
type (for looks), but I don't think that should change anything. Injectors, fuel 
pump, sensor, distributor?  Not sure where to start.
