I was gonna put on my profec b to control my boost because it was spiking at about 16 psi. But yesterady it stoped and now I am only getting 10 on primary and 5 on secondary? Any thoughts on what may have happened? I'm not real familiar with the vacum hoses on these cars. Where can I get a diagram?

 

do a search for a diagram, and diagnosing secondary problems is a PITA to do. YOu might just want to do a vacuum line job to get it out of the way, cuz tht could be your problem. But u need to T into some lines and get some readings. check make sure your actuator rods are working correctly etc.

There were some really detailed posts, one being mine on how to diagnoss secondary problems. I'd type it all for you but im lazy and im tired
mebbe tomorrow

And welcome to the board friend!
