When i removed the first one cylinder 1 my car never even hesitated for a second when i removed the 2/3/4 my car wanted to shut down so from what i understand you are saying is the one that does not make a change in rpm might be a problem and on my car that would be cylinder 1 either the injecto or the spark plug

Yes, no change. That cylinder is not contributing. Cylinder 1 is missing. Move cylinder 1 plug to cylinder 2. If misfire moves to 2 it's the plug. If it stays on 1 check injectors.

By checking I mean swap injector 1 with injector 2. If misfire moves to cylinder 2, where #1 injector now is, then replace the injector. Car fixed.

Do I need to remove the fuel fuse?

You are not removing the fuel rail or fuel line to do a compression test. You do not need to remove the fuel fuse.

Was the compression test about 150psi on all cylinders?

@@roscoesrepairs yes Rosco ! But the scanner reported me short circuit in cylinder #3 P0203 . It's really driving me crazy as well . Cos the car has only 75,000 miles.

​@alrodney777 OK, thanks for that code. P0203 means it is something with the injector wiring on the 3rd injector. If the error were P0302, it would mean there was a misfire on cylinder two. The code you got is, for sure, P0203?

With the engine running, pull plug wire off cylinder 3. Does the engine run differently or stay the same? If it stays the same, then that cylinder is the one with the problem. If P0203 is the code, I would swap injector 3 with injector 4 and see if the error goes to cylinder 4 (you should now get an error code P0204.) If it does, then replace the injector that is now in cylinder 4. It has an electrical issue. If, however, the code stays P0203, the problem is in your wiring to the cylinder 3 injector.
