on a test drive with a friend...looking to buy a 97 GS...

i drove it for the test drive and noticed it was only getting about 4.3lbs of boost...

being the idiot that i am, the only thing i could think of it being would be the BCS...

any other ideas?

buick?? its not a pontiac.

ok i have no clue either but my guess would have been that too.

4.3? That thing have a digital readout?


It could be a vacuum leak, I think. From what I've seen, a bad BCS wouldn't let you get boost at all, or it would flutter a lot. And the PCM demanding boost dump, you would see the boost peak at normal before it drops off, then flutters just a bit. But I haven't seen everything, I'm sure.

yeah digital readout...

he is going to buy it this week...its super cheap...

like 2500 cheap...

175k, but the tranny shifting PERFECT...

only problems we saw were some previous body work/rust, and leaking valve cover gasket

Boost control solenoid, when mine was bad , i was getting half boost, 99%
of the time thats the BCS.

Man... I miss my regal now. i would jump on that for the price. The doors and such can be painted. I would also ask why the Airbag cover is up. I see no heated seats, probably not a monsoon sound system since the deck is removed. Interior looks very clean. 97 was also the first year for the car, so not sure if any issues from that. I know that there were some oddities with the 97'* that the 98+'* didn't have. That one looks like it escaped the exterior mounted antenna. Not sure what the other ones were.
