Today I did the final clean of the coolant system, ran water through it for about 1/2 hour until it ran perfectly clear. Then fresh coolant (red OAT).
Its lack of power is a bit odd, I tried unplugging the maf to see if that was it but it got considerably worse with that unplugged so I'm guessing that's ok. I'm waiting on the nanocom to arrive.
I did a check in the coolant for exhaust gases with the proper tester, no signs of them (which I'm guessing is a good sign!)
It takes some cranking to get it going first thing in the morning, a good ten seconds or so then it eventually sputters and fires up. Then itll run perfect all day. It might be theres an air leak in the fuel system? Any other thoughts anyone?
