Well i just did a compression test on my KA24E and here are the results.

Cylinder #1= 200 psiCylinder #2= 195 psiCylinder #3= 195 psiCylinder #4= 197 psi

So i little bit about the motor. I swapped the transmission about two months ago and its fine and dandy, but i just swapped the head on my car becasue to valves on the other head popped out on the botom of the head. Not really any smoke came out or anything it just started running like it had a big loss of power. Its getting spark on all spark plugs. I ran this test that my dad said should show something, i would unplugg one plug from the distrubutor cap and if it made the engine start puttin then it works. so i unplugged the second cylinder plug and it didn't change the eninge's running. so i think that it might be compression. maybe a injector is clogged but i will check that out to. but i was thinking about just selling it cause its my daily driver and i need a good motor. and i would just swap another into it. But i Got my license suspend for 3 months so i will just fix it myself. So i need to know what yall think i should check out on the motor or run anymore test or what i need to fix to hve running good again. Thanx...

The compression on #2 looks good so i would think it's probably the injector if it's getting spark and the spark plug is good.
