Message:
I just bought an 87 4x4. I like it so far... I bought it figuring it would have a few issues. No problem.
One thing I can't figure out is this sound of hissing air that sounds like it comes from behind the dash, directly behind the steering wheel.
The truck doesn't come up to speed well, max 65 on the highway, and really slow uphill.
Also, the sound increases the more I step on the accelerator, pretty loud, and dies out slowly when turning off the vehicle. pshshshshsh.....
any ideas?

The pedal is a little hard, and it is right inside of the booster...hmmm...you've given me a place to start, thanks.
As far as the low power at highway speeds, and just generally being able to put the pedal to the floor and not have more power... I've been searching keywords and I'm kind of leaning towards a bad catalytic converter. The symptoms sound awfully suspicious.
Thanks again.
