vacuum readings
Tonight I hooked up a vacuum gauge on my engine.
When the car was at operating temp, the needle bounced between 14-15. I know the needle should be steady but what does the bouncing indicate?
What other tests can I do with the vacuum gauge that will tell me different things about my engine?
FIW, my cam specs are 274*/284* .519/.523 lift 110 LSA
