The computer should reset itself after 100miles so that all of the systems recalibrate themselves to work properly after the battery is disconnected. If the engine was flooded it will start rough and may day when close to idle until it has completely burned off all of the flooded fuel. If there was any other fluid that reached into the engine ie.. water starter fluid which you SHOULD NOT use on a rotary engine and if you feel you must pease only use a very small amount one or two sprays, the car will run rough until whatever it is burns out. By 200miles you should be running smooth again.Iif there are any warning lights remaining on you will need to troubleshoot those and go from there.

have you disconnected the battery for more than 5 mins before the trouble started, if so you have to reset the idle value by disconnecting the negative battery cable, put a shop towel between the battery post and cable, run a jumper wire from the negative battery cable to the positive cable ,which is still connected, leave it on there for 5 mins, remove jumper wire, reconnect negative cable to battery, when you start it, turn the key to the on position, wait for some of the lights by the speedometer start to go off, then start it

Have the shop check fuel pressure at the fuel rail. Maybe the pump impeller has failed. If fuel pressure is good, your timing chain/belt may have slipped.

Well Mike" a few things to check could be Breather on fuel tank /fuel return to tank pipe/ as pump can pump high pressure and excess has to return to tank and it sounds like yours is overfueling./take air cleaner off and all pipes and check for any thing partly blocking air flow/also check any black hoses coming from the engine breathers/going to air in take/make sure all cylinders got good compression

i would say that you have a bad fuel pump or if you have a carb on it the float inside the carb is stuck check these and i'm sure you will find it's one of these.
