Erratic Idle

[biggygt4]

I'm just wondering if any one could help. When I fire my Glanza up the idle sits at about 2k but after about a minuite or two it drops down to 1k but starts to bounce erratically between 1k n 2k. My manifold is cracked, is the blowing causing the idle to bounce or could it be something else? I hope someone could shed some light. Cheers

Sounds like a vacum leak on the inlet Mani mate check all the vacum hoses for splits

i'm just waiting on a new manifold but i was just wondering if it could of been caused by something else and i can get that sorted when it goes into the garage.

Vacume pipes as matt said, theirs loads of them get some wd40 and spray at a few pipes at a time, if you hear the engine changing revs then it will help you locate where abouts it is, if that makes sense
