Oldsmobile cutlass supreme 1980, cant go over 15mph

[mickeypowa]

Hi guys!

My car has been sitting for maybe one year and was not able to start.

I made tests with plugs and I had no spark, so I changed the distributor cap, ignition coil and the brush/spring (which was rusty) and then eureka! I was able to start again !

So I tried to drive, as the idle was a little bit rough and stalls sometimes I was thinking driving would help.

But impossible to go over 15mph maybe, I have absolutely no power. The engine turn rough when I rev it and no power.

What do you think it can maybe ?
Maybe I should changed spark plugs ? Or what else ?

Thanks a lot

Mickey

New spark plugs and wires surely can't hurt. What about fuel? Did you empty the tank and put new fuel in it? Bad gas could be an issue. Causes weird problems and gunk could clog filters, etc.
