Yep, 99.9% sure it will be your TPS (throttle Positioing Sensor). You need to seal it up with a tube a silicon. Did you just give your engine a wash? Is your dual Fuel?
I had this exact problem when I first got my 93 80Series. I would splash through some water and it suddenly wouldn't rev past 2100rpm, drop to idle, nearly stall and then kick back up to 2100rpm again. The next day it would be fine as it would have dryed out buy then. I found that it only happened while running on petrol and NOT LPG so that ruled out a few things.
Good luck.

Where's the TPS and what does it look like. I have the same problem with my 93 80 series.
