Okay i put the computer on my car and it says misfire on cylinder 2 and then ichecked the compression and it was at like 60. Why do you think its so low?

 

low compression can usually be because there is blown head gasket,burnt valves,Old (worn) and weak rings,Crack or opening in the head - but that doesn't necessarily mean water in the oil or oil in the water,Cracked cylinder,Burned or cracked piston,Cylinder worn or out of round,Sticky valve,Broken or worn valve spring,Bent/worn push rod,Worn camshaft or a broken lobe on the cam, Worn or bent rocker arm, Collapsed lifter.

All of this things can be the reason for low compression on a piston or all the pistons.

 

How do i figure out what it is?

 

Start taking the engine apart.

 

check compression in all 4 cylinders, could eliminate some of the issues posted above, and did u take out all spark plugs before doing test?

 

Put a teaspoon of oil in the low cylinder, then redo the test. If your number jumps up, that usually indicates a ring problem. A leak down test should help identify a valve problem.

 

your engine would be running pretty rough with that low of compression on a cylinder. try retesting multiple times. if you have only a couple misfires it probably indicates something else

 

It said misfire on cylinder 2 so i test that one and cylinder 3. cylinder 3 was good but cylinder 2 was at about 60. I checked the spark plug and it was burning good and i checked to see if it was a bad coil pack and it wasnt.

 

i put my money that its the head gasket or the head . and as mention before only way to find out is take the dam thing apart lol

 

Low comprssion will cause misfire and there is no way to really take care of it without at least dismantling the top end. It could be due to bad rings, but when only one cylinder is involved it usually a bad head, bad gasked, or a valve train problem. All of which requre dismantling the engine to some extent.
