Is this Correct for doin a Compression Test, some threads contradic one another
Halfords Compression Tester tool will do?
Disconnect Fuel (EFI Fuse or Ignition Module)?
Take out all spark plugs or do one at a time with 5 always remaining?
Hot engine?
throttle fully open for every cyl?
Good Battery
Results to be Expected
Standard pressure:
1,079 kPa (11.0 kgf/cm2, 156 psi) or more
Minimum pressure:
883 kPa (9.0 kgf/cm2, 128 psi)
Difference between each cylinder:
98 kPa (1.0 kgf/cm2, 14 psi) or less
189 -190 on most engines that are in tip top condition
And each Cylinder is very close to one another no big differences
Missing anything?
