One or more cylinders is not working. There are many causes of this.

For example...

One or more injectors are not working.
One or more sparkplugs aren't firing for a number of reasons (bad wire, bad plug, bad coil)
You could have one or both headgaskets blown.

Is there any steam coming (white smoke)out of the tailpipe?

How and when did the problem start?

most likely head gasket.. check radiator to see if u need fuid.. check oil for water.it should look like gunk or slugde..remove plugs and check to see if there is water in the cylinders.. if u take ur heads off for gasket replacement .. do ur self a favor and take the heads to a machine shop for pressure check and and have them redone.. u dont want to go through all that work for nothing..
