Car killing iac valves
91 chassis, 00 motor, ms3x
Valves are getting stuck open. 3 used ones, 2 cheap Amazon ones and now a $250 parts store valve. No vacuum leaks, the valves are sticking open.
At this point I'm thinking my blow off valve is faulty and killing them but I've already changed it once.
Ready to burn this car the **** down.

One thing you need to remember is cars don't respond to emotion. It does you no good to get angry at it, the problem won't fix itself. I find it always helps to step back and work on something else. Attach a log and a tune of the "stuck open" IAC, I personally have never seen this, even with cars without BOVs. The NB valves are simple solenoids that open more or less with varying levels of duty cycle. Let us look at a log and make sure it's not actually commanding extra duty cycle for some reason.

You said valves are getting stuck open, implying they work at first but get stuck open after a bit of time? How long are they good for before sticking open? You've confirmed this with all of the valves removed from the vehicle?
Curly's right about getting a log. I just want to understand what's happening completely.
