Bumpy..

Please help vacum layout also..

so i just got a LS400.. before any maintance i figured id just give it a good hose down..

i did that with the engine running (had just started it so it was cool)

i let it run for about an hour after the hose and all was good..

even turned off and on again. and no probs..

so i go to get some food tonight and Bam..

Surging Idle from 1100-1800 and OUch when i put it in gear..

so i get it back home and i let it run for a bit surging..

i have a few vacume leaks and missing vac lines but thats not the cause as they where bothced before the wash..

could it still be a bit wet.or something got wet wile the rest was drying cause it was fine earlier..

. or could something have broke..

is there a link to a complete rundown of the vacum lines so i can replace and check them all..

also side note what is the thing with 2 vacume lines directly under the IAC connected to the coolant system..

(i saw its completely broken..)

could my iac have gone to crap from a wash..
