Misfire HELP

if you have real misfire, there could be a few problems. i'd suggest you check these:

- faulty plugs/wires
- ignition timing incorrect
- camshaft/timingchain worn
- burned valves, not closing the chamber correctly, thus under heavy use igniting the mixture in the exhaust. this may be caused by poor mixture, wrong ignition timing or deficient refrigeration due to partial obstruction of the cylinder head cooling. As a consequence, the valve is cooled inadequately. Or, running "dry fuel" such as L.P.G resulting in inadequate lubrication of the valve seat. (can happen too if your engine requires leaded fuel and you ran it on unleaded.

if I had to bet, i'd place it all on burned valves, as the 3.8 caused me that kind of issues twice. i threw the engine out and installed a V8 instead ^^

if it happens after the engine is warm and is more noticeable under hard acceleration that points to the wires and cross fire induction
