1986 buick lesaber 75000 original miles she is my baby, she started to run real bad, shaking stumbling, hesitating. the check engine light came on and off and on as i was driving, and the code i got was "#32 barometric pressure, sensor circuit failure, OR exhaust gas recirculation {EGR} valve diagnostic switch closed during engine start up OR open when EGR flow requested by ECM. OR EGR/EVRV"

the EGR valve is about one year old. this is what i did: Started car, opened hood, look at shaking and stumbling engine. looked at EGR valve and it was fully OPENED.. at normal idle. i pulled of the hose and the engine ran smooth and the power was back. took the car for a ride and it was great but the hose is off the EGR valve and i know thats not good. now what do i do. thanks

There should be a vacuum control 'switch' not too far away from the valve, follow the hose to find it, it's most likely your problem.
