Hi
It turns out that the compression in cylinder 4 on my 560 sec is 1/10th what it should be.
Right now I'm just trying to get it through inspection and it fails because of the smell of unburnt fuel.
I was thinking I could just unplug the injector wiring, but as I found out it has K Jet mechanical injection.
Will removing the fuel line to cylinder 4 and plugging it cause pressure issues in the system?

No you don't end up with more fuel in the remaining cylinders. Otherwise if you had a clogged injector the car would not run. I think I would be trying to figure out that compression issue yesterday. good luck!

Ok, I'll look into plugging it at see if the smell goes away.
The shop that tested it said it most likely needs new rings and just a general overhaul. I just want to get it through inspection right now and deal with it when I have the time and $ to do so.
