Hi everyone
I was following Ogre's guidance on setting the idle on my v6 GT 308 replica and was wondering which vacuum pipes need to be plugged?
I'm not sure as a newbie to these cars - can anyone help? maybe with a pic?
Thanks
ian

Setting the idle on these engines is nearly always a bad thing. What are you trying to correct?

If long enough, all hoses should have a small section cut from the rubber end, to assure a tight fit
the EGR system is crap & if you do not need this for inspection,emission inspection,,eliminate it & block off the cross over pipe
hole & the hole under the plenum,
very often the EGR system is defective the EGR tube leaks, the EGR itself is glogged,, the EGR vacuum solenoid is a troublesome POS,very poor design,, of course a new one only cost $150.oo
wealthy men seem to like the EGR system !!
every hose needs to be checked on any old car,, you need to be certain every hose is leak free
what RPM does your car idle at,,when warm
do not forget to check the hose & flter connections that run to the brake booster
the hoses under the plenum aremore trouble free than I ever thought but they do have some leaks
do not forget tube connections at the emission canister over by the airfilter
many hoses have a small split difficult to see check for this
very often a hose is just not tight enough on the pipe it is pushes on and trimming the ends will help
trimming the ends is a long term fix to prevent future problems
give a little more info for more help !!

Thanks for the replies.
I don't seem to have an egr fitted(uk spec) and was trying to follow ogre's advice where it states to set basic idle and the iac, you run through a relatively simple process. However the first step states that i need to plug appropriate vacuum lies and hoses. I wondered which ones.
Idle when warm at present is around 1300 but it is not particularly stable and periodically drops and on the odd ocassion, stalls.

Setting idle stop is often a bad move.

Likely have vacuum leak. Some leaks can be temp sensitive.

See my Cave, Vac Leaks for some ideas.
