I was coming back from work and about 10 minutes after i started driving the engine started shaking and the CEL turned on. It did it before for a very short period of time (about a minute or so) but this time it did it until i got home (and i never got a CEL before either.)

I pulled the codes from the CEL and it gave me code 7 and 2 (or 72), anyone one know what it means?

According to my mechanic, it could be a faulty coil pack but he also noticed the water level in the radiator was low even though the reserve tank had plenty so he thinks it might be the thermostat and the engine is over heating (even though my temp gauge indicates a good temperature.)

Any help would be greatly appreciated.

After some testing i think i found out what the problem is... Its something with the wiring.

I tried reverting back to an older spark plug in case this one was defective but it turned out it was fine.

I then tried unplugging each coil pack individually and the RPMs dropped on each cylinder except for the middle one on the left so i thought theres my problem...

I then switched the pack with another one on the opposite side but once again the left side was the faulty one... So that eliminates the coil pack as being the problem (thank god, these things are expensive.)

But now i have no idea how to find the problem in the wiring, theres miles of it!

Once again, any help would be very appreciated on finding where the problem could be coming from.

Oh and apparently (according to this http://www.zealautowerks.com/ecu_codes.html) its cylinder 2 misfire... sounds about right.
