idle spike after tb mod !!
yesterday i did the tb mod on my 87 t2
i follow the write-up on fc3spro.com
when i start the car my idle spike between 1000-1600 rpm
so i take off the thermowax off and re-route the 90° coolant hose on the rear housing to the BAC valve
i think that my idle problem was not the BAC valve because it connected to coolant
do i need a tps adjustement maybe??
any help will be aprreciated !

Yeah, you might've dislodged crud that is propping the throttle plates open.
It's a good idea to shoot the bores with a couple cans of brake or carb cleaner just to get all the crap out.
Also, use the throttle stop (on the primary) to adjust idle RPM's.
