I was checking out some ignition modules to see it they were good and when I went into boost the car mildly backfired and after that I lost boost. My boost is set around 25 psi and now It generates only 10 psi of boost. I found the boost solenoid fuse was blown. I replaced it and it blew the replacement as soon as I went into boost. After this, I put on a different boost solenoid, went for a test drive, and it went into boost normally to 25 lbs. a couple times. I assumed it was fixed but when I went out again, it returned to the 10 lb boost limit with the same result -- blown fuse. Anyone know where I should start looking for the problem?
