I have a 1984 Buick Electra Estate Wagon that has been sitting untouched for 2 years. When I fire it up (which can take a bit) there sometimes is a high-pitched sqeal correspondent to RPM : when I rev it increases directly but sometimes it goes away after running for 1-2 minutes. I am not currently driving it, but perhaps will in future. Would appreciate enlightenment. (engine is 307)
Yes it sounds like you may have a belt issue, may have deteriorated of the the two year span, on the other hand it may be a pulley issue two, you wont know until you change the belt

Your transmission should be either a 200r4 or 700r4 which are not controlled by the ecm. Shifting is controlled by a shift cable connected to the throttle body.
It needs a good tune up such as oil change,new wires and plugs, air filer,fuelfilter,and if possible try to drain gas lube all tire rod ends an as much as the chassis that has grease fittings.
change
out ur fuel filters, theymay have trash in them, especially if u ran it low
in gas..it may also be the fuel pump going out, check out the filters
first..goodluck.
