Check Engine light on and blinking
no a vaccum leak would cause a unsteady or rough idle, it sounds like either something to do with spark or fuel. go to autozone and get it checked out, then we will find out that way for sure what it is.
replace the 02 sensors a faulty 02 sensor will make the engine misfire. I had the same problem then replaced both front 02's an now im runnin like a champ. I also have rear 02 simulators.
You stated you put the rear O2's in the front. You did unplug them from the rear O2 connectors, moved just the O2 sensors to the front and then plugged them into the front O2 connectors, correct? If not then this could be your problem. At WOT the O2's are not used in fuel delivery calculations. This maybe why it is runs ok at WOT but like crap everytime else.
Just something else to look at.

Check your wires and plugs. The wires could have laid up against the primaries after the LT install and burnt through it. Check for cracks or burnt spots on the wires. Pull your plugs and check for cracks in them also. You could have busted some of th porcelain on them when putting them back in. Check every connection that you unplugged during your install. It could have came loose.
Start with the easy things first, then go from there. And I suggest not going WOT until you find out what the problem is.

FYI, you probably shouldn't bump your thread every 40-60 minutes - it will get read, don't worry.
These guys have given you a lot of advice - I'd suggest taking it to get the code read, and go from there, otherwise you're just grabbing in the dark.

Ive seen several posts of people telling you to re-check your plugs and wires and no posts that you have done so?!?!?!
random missfire codes are caused by plugs/wires/coils so you need to check them.
are your plugs gapped properly??
are your wires laying on the exhaust manifold?
are your wires hooked all the way in??
chances are your coils are ok so i would start with the plugs and wires first..if they are ok than i would deal with the coils and/or possible injector than go from there.

im about 3 hours from rochester. IM heading there next friday to new era performance for tune. Saturday im having a engine shop who did my mod install pull out my plugs check them for damage and gap. I checked all the wires i could reach all seemed tight and in place but maybe the pass rear one isnt? Its just odd how at higher rpms its good but low not soo good. What do cracked plugs do to the motor?
