ok everyone did tune up and engine still runs like doodoo.still no power and has rough idle.did the finger in the hole test and rear rotor definately has significantly less compression.what are the possible causes?can it be only apex seals or are there other possibilities?if it is apex seals am i looking at a total tear down?again i thank you in advance for your help!!!!

 

Before you go off hunting ghosts, get a compression check to be sure.

And yes, if it's the apex seals, it's a teardown..
