1 of many things......

my first guesses would be

1) - fouled spark plug
2) - Faulty spark plug
3) - Wrong gap on spark plugs
4) - Spark plug wires hooked up incorrectly, sounds goofy but happens.
5) - Need to check dwell/timing

Start here...it's the basics

You need to find out if you have points setup......take it to a shop, they have equipment for you..Probably cost you $20

if you're having these problems on the 82 caprice in your signature then points cannot be the problem because they stopped using those in 1973. GM went to HEI ignition in 74.

go to a autoparts store they will tell you the gap size for your ride, just buy the gap tool and redo the plugs, make sure your wires are tied away from the block.

i got a hei distributer cap (w/ coil) if that turns out to be the prob.. if not, duece is right, and a plug gapper would cost ya every bit of 2 bucks.. and to answer your question, (how could the gap be wrong if i bought the right plugs) the right plugs basically means its the right size and produces the right amount of fire for your car, but you have to gap every set you buy.. be easy man. good luck.

Your Gap is probably 35 or close to it. Regardless what it is.....let us know when you find out....

Just because you have HEI doesn't me they don't have problems.....I had one that missed constantly.....if thats the case

Check -

The cap for cracks..take the cap off and look inside on the gold terminals, if you're missfiring, one of them will be black.

Check the coil....you will need to ohm it out to make sure it's good.
