It should have 150 PSI per cylinder. If it has a reading of 90 LBS. are less on any given cylinder, Then the engine will idle rough at an idle. / engine miss.
You can't have anymore then 15 LBS. difference in any one cylinder.
150 LBS per cylinder is a good reading on a fresh are good running engine that's in good shape.
You may have only 120,130,140 or 150 LBS. That is your highest reading, And engine will run fine as long as there is no more then a 15 LB. difference in any given cylinder.
Hope this answers your question. A 100 or less LBS means the engine is tired / Worn out needs rebuilt.
