Engine misfire

Welcome to 2CarPros.

No, a cam sensor wouldn't cause this. Tell me if the compression test was done both dry and wet and if there was any change.

Take a look through this link for causes and testing compression.

Also, here are the directions specific to your vehicle for testing compression. At the end, it discusses possible causes of different problems. Also, it provides the manufacturer's specs.

Engine Compression Test

1. Charge the battery if the battery is not fully charged.
2. Disable the ignition system.
3. Disable the fuel injection system.
4. Remove all spark plugs.
5. Turn the ignition to the ON position.
6. Depress the accelerator pedal to position the throttle plate wide open.
7. Start with the compression gage at zero and crank the engine through 4 compression strokes, 4 puffs.
8. Measure the compression for each cylinder. Record the readings.
9. If a cylinder has low compression, inject approximately 15 ml (1 tablespoon) of engine oil into the combustion chamber through the spark plug hole. Measure the compression again and record the reading.
10. The minimum compression in any 1 cylinder should not be less than 70 percent of the highest cylinder. No cylinder should read less than 690 kPa (100 psi). For example, if the highest pressure in any 1 cylinder is 1 035 kPa (150 psi), the lowest allowable pressure for any other cylinder would be 725 kPa (105 psi). (1 035 x 70% = 725) (150 x 70% = 105).

* Normal - Compression builds up quickly and evenly to the specified compression for each cylinder.
* Piston Rings Leaking - Compression is low on the first stroke. Compression builds up with the following strokes, but does not reach normal. Compression improves considerably when you add oil.
* Valves Leaking - Compression is low on the first stroke. Compression usually does not build up on the following strokes. Compression does not improve much when you add oil.
* If 2 adjacent cylinders have lower than normal compression, and injecting oil into the cylinders does not increase the compression, the cause may be a head gasket leaking between the cylinders.

______________________________

Now, a wet compression basically involves injecting about a table spoon of oil into the cylinder and rechecking. If the compression goes up, the rings are bad. If it doesn't, it could be a head gasket or a valve issue. Since this is only related to cylinder 1, it won't be a timing issue.

If the engine runs, and it should, here is a link that shows how to test for a bad head gasket.
