M30 troubles

[JoeMadoo]

This m30 is ideling rough and has no throttle response, as in hit the gas and it almost dies before it r3vs up. I need clues...

Things i've checked:
- Vacumm is 15 at idle.
- I hear what sounds to be a vacuum leak around the FPR but there are no leaky hoses....
- Wires work
- Rotor is new, cap has slight wear but seems ok.
- Played with the timing gear moved from tooth to tooth but still runs the same. I even checked it with a timing light.

I NEED HELP!

check the rubber boot really good were the idle control valve is and around where the hose clamps are.

Fpr? And or the diaphram inside of it?

Well i figured it out... The number 4 fuel injector plug was unplugged. So the whole time i was running on 5 cylinders. I still beat a new civic si, haha.

But now i have anther stupid problem. After merely removing the radiator and disconnecting the 2 radiator hoses (because i thought the timing was off so i had to make some room) my car overheats and there is no coolant circulation anymore... And i did fill it back up and bleed it.
