What happens if your spark plug has a p0304?

It also can cost money to ignore it, since driving with a misfire can damage the vehicles catalytic converter. The engine is also not firing all of the fuel, so raw fuel is also passing through Cylinder 4 into the exhaust. Mileage may suffer as well when your Spark has P0304 as well.

What should the compression reading be on a car engine?

If a cylinder has low compression, inject approximately 15 ml (one tablespoon) of engine oil into the combustion chamber through the spark plug hole, recheck the compression and record the reading. The minimum in any one cylinder should not be less than 70% of the highest cylinder. No cylinder should read less than 100 PSI.

How to diagnose a hard to find misfire ( GM 4.3L )?

Removed the spark plug wire from the #1 spark plug. Attached the spark tester to the spark plug wire. Grounded the spark tester with a battery jump start cable directly on the battery negative (-) terminal. Had my neighbor crank the engine while I observed the spark tester. The result was: I had spark!
