Sounds like you distributor cap has failed about $12 to $26 at any auto parts store don't forget to change the rotor also.

found the problem, I replaced distributor cap and rotor since it looked bad, still same problem, after doing a compression test found out it's a exhaust valve, at 280 000 miles it's time swap the engine. to the auto wrecker I go

Seen the shim adjusted valves on these engine "hold" their clearance for 100,00 miles but important (yet neglected) service after that. Valve gets tight and then burns or causes a misfire/ possible emission test failure particularly at idle (high hydrocarbons).
