In 95 (speak) it indicates MAP sensor circuit-signal voltage low-high vacuum.

Possible Vacuum leak. Check the vac hose on the MAP sensor. Also unplug the map connector and clean it out with elect.parts cleaner and plug it back in and reset the computer. Map sensor could also be bad.

thanx a lot guys,
he had his tranny serviced and they (of course) wanted to go deeper :eek:
since he left the station it stalls with no throttle, and 34 is prevalent.
definitely could be a vacuum problem - those buggers probably pulled a line!
i'll get back to you...
