stupid idle

o.k here's the scenario: 1993 ex sohc vtec, idles between 3000 & 700 rpm(fluctuates) and startup idle is 3500rpm, had the coolant lines disconnected from the throttle body, reconnected them cause it did that when it was cold but now it continued? can't drive consistant in 1st 2nd or 3rd the car surges when idle drops then pulls ahead again. no cel...any ideas are appreciated.
