So my car was working fine Saturday morning, I changed the IAC Saturday afternoon and drove home from a friend's place. On the drive home my car ('87 GN) ran terribly. At 10 psi boost the car starts popping, almost like a backfire and my scan master shows 10 degrees KR. Sometimes it works normally and I can get to 20 psi boost, but the whole car surges before it pops again. I have blown vacuum lines off the vacuum block on the throttle body once and I also blew the hose off the outlet of my intercooler. I am totally at a loss. I don't see any visible connections loose. Any help is appreciated.
