Cylinder 3 or 2 misfire?

Hello AWALKER121212,

According to my information you should have 198 PSI for compression with no more than a 14 PSI difference between cylinders. The minimum compression you should have is 142 PSI.

So, it is more than likely misfiring because the compression is so low.

Since it is happening on multiple cylinders it is something that is affecting the entire engine.

I would re-do the compression test to confirm your findings. If you find you are getting the same readings, I would re-do the test again but this time I would try putting a capful of oil in each cylinder right before you test it.

If the pressure rises after performing the test with oil added, your piston rings could be too worn. If not, it may be the valve seats. Which means you will need to remove the head and have it rebuilt.

A head gasket is another option. If it is a head gasket you will have Nitrogen Oxides or NOx for short, in your cooling system as part of the combustion process.

You can test for this using a special color changing liquid called block tester.

Here is a link but any auto parts store will have it:

https://www.amazon.com/Block-Tester-BT-500-Combustion-Leak/dp/B06VVBSFTF/ref=asc_df_B06VVBSFTF?tag=bingshoppinga-20&linkCode=df0&hvadid=80333123589171&hvnetw=o&hvqmt=e&hvbmt=be&hvdev=c&hvlocint=&hvlocphy=&hvtargid=pla-4583932709121118&psc=1

Make sure to reduce the amount of coolant in the system so it doesn't get sucked into the tester.

Unless the compression test was done wrong or the tester you have is broken or wrong, you have a compression issue. If you are renting it from an auto parts store it could be a bad tester because people rent them and throw them around. You might want to just get your own if that's the case.

I found one for you. It' s a good brand Pittsburgh Automotive.

I would do these couple things and see what you find. Let me know if I can give you any additional information.

Thank you,
