got some vacume lines off or mixed up the sticker should be by the wipers if not lmk i have mine out side i can copy it for you.

its not vaccum i checked all the one where he was working and they are all connected i checked the codes and it seems to be getting a code 45

[5sp. mini]

is that overboost or fuel cutoff. or the a/c code? DG said it,s overboost code. like we didnot know that.still say vac. line off or miss routed

[scarface1689]

so you u still think its a vaccum line or could possibly be the solenoid

[5sp. mini]

i wound think it,s not electrical cause boost is a vac. contraled. try running streight vac. to waste gate can and it will only make 7 to10 lb of boost.ifline is off it will overboost.i just pulled my motor on my 85 z and the pack of vac. line on the back of the valve cover were tons a cranked or miss installed or broken line will give you over boost

[scarface1689]

how do i run straight vac to the waste gate

[5sp. mini]

a main vac. port .off the intake or the heater valve line.this is a suck through style right. come guys help me out here i,ve been out of these for a 2 years now.
