Is it the clipped on to the body of the car. If u look directly down at the engine it\'s to the right and has a pipe coming out of it. If that has come off then the engine won\'t start, plus u might of flooded it by now.

think you might be talking about the idle stabiliser thing - it\'s bolted directly onto the inlet, right?
 
you\'ve probably flooded the car, so get the plugs out and soak them in some brake cleaner. while that\'s happening pull the main EGI relay out (in a small box just below the passenger side strut tower) and turn it over a couple of times.
 
if the idle stability solenoid is bust, you\'ll be able to start it on the throttle and keep it from dying by holding the revs up.

thank for the help mate, we see how it go\'s and do you no if the idle stabiliser thing can make a buzzing sound

it\'s a solenoid, so it could start buzzing away if there\'s a problem with it. you can just get rid of it and blank up the hole, but you need to fiddle with your idle settings to get the car to run and it\'ll be a little rough when it\'s cold.
