Been working on a 1981 Turbo Spider (Turbo removed) barn find for a while. Did a compression test and got readings of 118, 115,110,95. Did the test with the engine cold , all plugs removed and held the accelerator to the floor. Plugs have been pretty oily and car runs rough at low rpm. I have changed a lot of external engine parts and I'm pretty sure I don't have any vacuum leaks. Car was sitting in storage for 15 years . I changed the fuel pump filter but I am about to change the fuel pump and another filter. My question is are the compression readings I got telling me the problem with lack of power is from an internal engine issue. Oh the engine does not smoke and has no leaks. Appreciate any help
