You never stated what your idle speed is?

Have you ever had the car idle at a proper speed and been able to start it w/o having to play w/the throttle?

You could also check for engine codes and also check the engine's compression.

Already checked for codes, doing a compression test tonight. Fingers crossed, is there any test for a leaking injector?

I don't know of any, but that doesn't mean one does not exist.

So I did my compression test, only got to the first rotor. I had the oil cap off, don't know if compression leaks through there but the highest number I saw was 70psi :/

Does it matter if I only took off the leading plug?

You only remove one plug per housing that you are testing.

You only showed the results for one rotor. Secondly, a cold engine produces lower compression, so ideally, you want to test when the engine is warmed up. if someone disagrees then maybe they will chime in.
