k so im getting kinda tired of this lol i bought the car (92 tsi awd with evo 3 engine) a few weeks ago and i noticed that the idle jumps from 1200rpm-1500rpm and i pulled a bunch of lines and checked alot of stuff and still can't figure it out.. now the lil screw on the throttle body thats suposed to have a rubber boot on it is turned all the way in aswell.. is their anyone in the hamilton area that can either help or come take a look and figure this out? im starting to get clueless and running out of time to get the etest done

Going to need way more info man a few hoses and some stuff could be anything.

If your in a crunch for time, you're allowed to extend a temp permit another 10 days. So total 20 days to get yourself sorted.

Hope that helps.

yeah its just weird, i tried the boost leak test and got nothing.. runnin out of options so im thinkin about just getting a fmic and change all the piping lol pissed off

got access to a smoke machine?

is the o-ring around the biss screw still there? are the vacuum lines on the throttle body connected?

Have you checked you ISC yet??? or your ecu for leaking caps yet???

Spray starter fluid in places where it may leak (BISS, TB Shaft Seals, etc.)....if revs fluctuate (increase) when you do then you've got a leak there.

If you've buried the BISS (little screw on the throttle body) then your ISC is pretty much toast. That or you have a serious boost/vac leak in/around the intake manifold/TB

disassemble your tb and spray the metal gaskets with copper spray, then reassemble.

i got an evo 3 throttle body coming un touched with sensors so ill try that
