When warmed up the idle starts bouncing. i have changed the IACV and the FITV has been removed . what are the other possibles causes that could be doing this.
cheers Jon

Low coolant, or a vac leak?

The above. Also, when did you change your IACV? Could maybe do with a quick clean with carb cleaner?

Mine was caused by a vacuum leak, turned out my oil catch can wasn't air tight

My son's did this just before the tell tale leak to show his waterpump was on the way out, even when we replaced the pump we had to air bleed the water system 3 times before it stopped .
Could be worth a check
Mine did it for a while and it was the TPS (throttle position sensor) out by 1mm.

I have had it twice once a water level issue, once a split vacume hose right underneath the pipe at the back of the inlet manifold, it can also be a bad connection on the fitv plug.

Thanks for all the replies. Ill have a look tomorrow and report back.
