All cylinders reading 55 psi. When running has a slight miss. Going to look at the dist. Can't figure out low comp. on all cyl. Starts easy. Any ideas?

Bad tester?

Has it been sitting for a longtime with out being run??? If you say yes then try this. Pour about a half cup of ATF in each cylinder. Put the plugs back in and let it sit 24-48 hours. Pull the plugs back out and spin it over to clear the cylinder. If it say for say a year the rings could be stuck and that will cause low compression if your gauge is correct that is
