Almost hitting 140k on my car. Car running strong. Since i love it so much i decided to do Seafoam to it. But before i do it, I'm planning to check the compression on each cylinders. And then maybe do the test after seafoam. Anyone knows the compression specs for out car? What should i expect?

 

135psi with a variation of 28psi between each cylinder. This is to be checked by cranking with the starter. FYI: It's much lower than typical for an 11:1 engine because the throttle will be closed since this car has an electronic throttle.

I have no idea how you disable the injectors to crank the engine though...

 

Pull the fuse for the fuel pump, that way u can crank it
