[rsi_scotty]

ok never had issues before with clios but here we go first for everything.

so im running a 172 cup .
its my track car and been forever faultless. its serviced after every trackday and never misses a beat,until now. so simply fitted the sm inlet manifold and now the car is idleing at 2800rpm?? have i made a rookie mistake?? its a bolt up modification?? iv done loads of engine builds etc and many mods just feel im missing something???
any ideas??

would the rotation of the throttle bodie cause any issues??

Spray around all the joins with wd40/brake cleaner and see if it alters the idle speed. This will help identify where you've got a vacuum leak.

Not silicone on the manifold to cylinder head joint? If so, I think we've found your problem.
