When I first start up my 1987 5.0 LX (115K basically stock), it will fire up and then the RPM's will often drop pretty low (~500 or lower), putter around, and sometimes stalls out. Usually, if I rev it a little when I first start it up, it's fine and good to go.
Now it's starting to do it more... sometimes even when I roll to a stop (ie parking) it will putter out and stall on me.
Otherwise, the car runs fine and there's been no recent work/changes to the system. It runs and idles fine once it's going.
Is this a timing issue? Fuel delivery?? I ran a fuel system cleaner and premium gas but it didn't seem to help.
Any suggestions are much appreciated! THANKS!
