Unflooded car, now runs rough (was: Read this!!!)

After doing the de flooding procedure,using 2 stroke oil in the plug holes and re placeing the soiled plugs with 4 bur7eqp [ALL I COULD FIND]it started up on the second attempt.imust note cars been sitting for about 2 mths.smoked like usuall for about 5 mins,and a little out of or around the turbos. I let it get to operating temp and took it for a test drive and straight away it starts hopping at around 2,500 - 3,000 rpm,boost drops visious backfire and of course power loss.on fast or slow decelleration,car feels fine,idles fine too.when accelerating slowly it seems ok right through the gears and rpm untill the peddle travel exceeds 2" and it hops again like mad. I drove this for about 20 minutes without little change.

Could this be because:

Battery went dead so phantom faults are now in the ECU

Dirty Fuel

Characteristics of a flooded RX-and if left oiling will it work itself out..

Run the tank thru, then refill halfway and put in some injector cleaner with it. Run that tank thru, and hopefully it will do better.

Basically, pull the negative cable off the battery. While the cable is disconnected, hold the brake pedal down for about 20 seconds. Then reconnect the cable to the battery and start the car again.

If its still running rough after a few minutes, try pulling codes to see if you have any stored.
