Normal engine compression would be 100-125psi
Why does your 97 Saturn wagon sputter through each gear?
There are several possibilities:Low fuel pressure would cause the engine to run poorly, the way you describe.Old, worn sparkplugs could contribute to poor engine performance.Faulty plug wires are also a potential problem.Dirty, fouled or plugged injectors are often responsible for poor engine performance.Check the compression, low compression can result in difficult starting and poor engine performance.Run an engine diagnostic scan; if the computer has not detected a misfire, you're probably having a fuel related failure.
Which engine design would have a compression ratio of 23 to 1?
The Diesel
What would make a multi-fuel diesel engine keep dying but starts fine?
Lots of things .. on a mechanical level When the diesel starts a glow plug causes the ignition after the initial start the glow plug turns off and the engine relys on high compression to heat the charge to ignition point. If your engine has poor compression you won't have ignition. Poor compression would be caused by engine / valve wear, burnt valve seats. Of course modern diesel engines are electronically controlled so it could be any number of other things. You can read out the fault codes from many cars by shorting pins on the service connector and counting flashes of a light on the dash.
Burned valve symptoms?
Engine miss, poor fuel economy, loss of power, and low compression on the cylinder with the burnt valve.

What is the compression psi on a 1990 engine?

Why is there no compression on a 2 stroke engine?
There is no separate compression stroke on a 2 stroke engine, but there is compression - the intake and compression take place on the same staroke, the intake on the first part and compression on the later part.
What makes an engine lose compression?
Worn cylinder bore, worn piston rings, poor valve seat condition, tired valve springs.
