93 Bonneville idling woes
Ok, When its sitting in park its fine, when you drive I havent noticed any issues with stalling till you go to stop at a light or stop sign, then the tack bounces below 1000 rpm, than stalls out, Ive been told to unplug the battery and reset the computer which I did, but its still doing it.
No filters been replaced as I just bought the car.....
Its been this way, where I need to shift into neutral and rev it above 2000 rpm, to keep it running...any advice?
Its sat during the winter, and im not sure if its just a filter plugs, or bad gas....it does it no matter if it has been run for awhile or just started it up...the idle is at 1000 to 1200 but when I go to stop it flutters.....help me please

You should do a full tuneup first. It'll probably fix your problem.
Plugs, wires, O2 sensor, PCV, fuel filter, air filter. In addition, you should pick up a throttle body gasket (dealer only, about $12 normally) and remove the TB for a thorough cleaning. After the TB is removed, remove the MAF sensor (large black square, 3 screws) and the IAC (idle air controller, it'* the cylindrical black thing). Leave the TPS on the bottom of the throttle shaft.
Clean the MAF sensor filaments GENTLY with a qtip and alcohol (not beer).
Clean the IAC and TB VERY well with intake safe/sensor safe cleaner. Then put it all back with your tuneup. Odds are, it'll run like a champ again.

Edit:
No Bosch plugs or wires, and the O2 sensor should be AC Delco only. All other parts can be your choice. Strongly suggest AC Delco or NGK plugs (both made by NGK) or Autolite. NAPA Belden premium wires are popular here.

Also, check for vacuum leaks. A little leak will cause your symptoms. Look carefully around the intake manifold, and follow the hoses to the vapor canister, vacuum modulator, vacuum reservoir on the firewall, ...wherever they go. Look for deterioration as well as disconnects.

Thanks, I grabbed some upper intake cleaner for the Intake(MAS), and spark plug wires, and spark plugs(AC-Delco)...grabbed all the stuff from Auto-Zone, as they reccomended a tune up as well....I will grab a pvc and fuel filter next if the problem still exsist'*.....the air filter is new and was changed a month ago....so if all goes well..the plugs and wires cures the problem...
I also put fresh gas in it (full tank) and added some gas cleaner stuff (yellow bottle, as the name skips my old mind..... :P)
So thanks for the comments....hope this works

Aim straight to the fuel filter if it doesn't Could be the pump having trouble pushing fuel through and maintaining pressure for a moment once you let off the throttle.
