I'd run a good fuel system cleaner through it and change fuel filter & plugs. Even w/high octane fuel, it still develops a varnish and plugs from sitting have probably have small amounts of corrosion on tips from condensation.

91 camaro 305 tpi runs rough at idle sometimes stalls and has power loss


tune up-read your plugs and then check your timing. use timing light and double check with scan tool-most 91 305's were high outputs which
requires higher octane than regular (fuel grade revelatnt to compression ratio and altitude) you may want to check fuel pressure could be a clogged filter or bad pump.

Car stalls while driving at high speeds


i would start by checking the spark plugs and leads. if that ok i would think there is a problem with the dispack that the spark plug leads fit to, if its cracked or any rust i would replace.
