Cylinder four compression is 70.
All other cylinders between 90-95.
The car misfiring after head gasket job.
Timing chain kit has been replaced.
There is a tiny space between the camp exhaust locking tool and the camp intake.

Hello,

It looks to me like compression is low in all four cylinders. I have included a compression pressure chart for your vehicle down below in the diagrams. Your vehicle should have between 130 - 195 PSI in all cylinders. As a general rule of thumb, compression in lowest cylinder shouldn't be less than 10% of the highest cylinder. I have also included a link for you down below. Please go through all the information and get back to us with what you find out.

Thanks,

I agree. All cylinders read really low? Where did you get your compression guage from? Also, can you provide the exact codes? With those readings I am surprise your vehicle even started? Let us know please.
