I was checking some engine temps with an IR gun and found some weird temps
The 1-2-3 side runs 500F about 2" down from the heads
The other side is getting weird..
6 = 350F
4-5 = 175F
What would cause the difference and the really low temps?
I pulled the plugs off 4 and 5 and it does change the idel but very very little and close to not at all??
Cheers
