the RV is running bad with spark plugs black
yes, their sucking air, 65;
Most common cause for a misfire on the 2.5L is oil in the spark plug holes do to leaking valve cover plug tube seals. You would need to replace plugs, wires, and valve cover gaskets in that situation.Most common cause for a misfire on the 2.5L is oil in the spark plug holes do to leaking valve cover plug tube seals.

No, the only thing a dirty PCV valve will cause is a build-up of gas pressure inside the engine which make seals and gaskets fail.
many cars todayhave aluminum heads and cast iron blocks these different metals heat and cool at different rates if you have overheated you may have warped the head or cracked the block
9/26/06 Never heard of that but I do know for a fact that year and motor had a problem with the head and gaskets letting coolant into cylinder wall causing misfire could also be seizing your plug and breaking during removal hope this helps you
exhaust leak. gaskets around the manifold. probly has a misfire at idle to i bet?
Head bolts bad about breaking and causing blown head gaskets,Valve guides wear prematurely causing bent valves and cyl misfire. If you own one and keep getting cyl 3 or cyl 4 misfire along with oxygen sensor needs replacing, Do a compression check before spending money on parts you don't need.
your valve cover gasskets prob need replace ment pull the plug see if their is oil in the spark plug hole if so new gaskets. if not then replace the coil pack.
Usually cars that have overheated will continue to run after you turn them off ---which is referred to as diseling (from disel engines). This is caused because the inside of the engine is so hot that the least amount of pressure causes the gas to fire and continue to run for a second or two. Not sure, but the misfire you observed may be due to pre-mature ignition due to the high heat that resulted in the pistons firing in the wrong order. You could have also overheated it to the point you blew a head gasket. Check for possible water in your oil or oil in your water. This is a pretty good way of knowing. Otherwise check the compression of each cylinder.
I hope your barb was a misfire.
Common cause is valve cover gaskets leaking oil into the spark plug holes. Remove plugs & check for oil residue around the plug & wire. You may find problem one just one bank or both. Removing plugs will drain the oil temporarily but it most likely will continue until valve cover gaskets are replace,
It means that more than one cylinder has a misfire history. PO301 would be cylinder number 1 misfire. PO302 would be number 3 cylinder misfire.
