mx-6 problems???

I have a 93 mx-6 v6 (180000Km) that drops down to zero revs then revs back up and runs fine again.It always starts fine and idles ok. I,ve tried two mechanics and its still happening....I've had the throttle body replaced but that didn't seem to help does any one have any ideas?

might be a distributor problem, just an educated guess from past experience though...

Thanks mate think you were spot on. I got the distrbuter overhauled and its running fine. Wish id done this earlier i,ve had the injectors cleaned the rocket cover gasgets replaced and the throttle body replaced by diffrent mechanics trying to fix it!!!!!!!!!!!

I have a mx6 4 wheel steer the 4 wheel steer warning light coming on when you drive has anyone got any idea what the cause is i have tried everything to fix the problem
