Remove your BCS. It only takes a 10mm wrench or socket. No need to remove the vac lines, just unbolt it so you can turn it and see the connector. Unhook the connector and read the resistance across the two pins on the BCS.

My 93 reads 28 ohms.
My 95 reads 30 ohms.
I have a bad one that reads 860k ohms, or nearly a megaohm.

What'* yours? If it reads like my two cars, you have a wiring problem OR the PCM is dumping boost for another detected reason. If it reads ALOT higher than my two cars, replace it.

I'll do it first thing in the morning. Thanks!

One more thing, if your BCS coil reads the same as mine, the valve itself could be stuck. Squirting some oil in each vacuum port and letting it soak may free it up. Good luck!

That vacuum line is disconnected somewhere. The diagram on your radiator support will tell you where it goes. There is only one piece of vacuum tubing on the car that shouldn't be connected and that'* back by the Evap purge soleniod...on the other soleniod below it.

Couldn't even get a reading on mine. Got a new one. Boost is back in full stride!

Thanks hugely for the help...I'll deal with that vaccuum line later, I'm tired now...lol.

Hot DAMN. Good to hear. Do go after that vac line later. It'* affecting your air/fuel ratio and idle quality. Also shortening your plug life and other things.

Good to hear. And you've contributed to my Supercharger page.
