Today I noticed it was really strugglin to get up a hill, one I ususally drive all the time with no problem. Wouldnt go over 2 grand, sputtering and *****in the whole way up (only 1/4 mile long hill) its the same anytime the engine is under heavy load, if i floor it either from a stop or rolling start or under powerbraking. I used to be able to hit 3k RPM under these situations with no sputtering. It has a rough idle sometimes as well.

Just replaced 02 sensor, plug wires, battery cable. Any ideas? Im gonna pull the plugs tommorow, and see If i can get a compression tester.
 






My '99 land rover freelander did that once, turned out to be a blown exhuast manifold gasket. Could it be that?
