i am having trouble with the freshly (500km) rebuilt engine in my 89 shelby daytona. TII. The compression on #4 was around 70 and the vacuum at idle was around 10-11. This mornign on my way to work, i noticed it was down around 16...and has been ever since. I did a compression test again, still low..Any ideas why it would all of a sudden pick up? thanks
