HG's replaced more problems...
Heads and gaskets back on, truck runs poorly at idle... I did not have heads machined, had them checked and they were at at 3 and 3.5 thousands. Idle is at 650 a little low, I have what I think is a faint knocking noise on both sides, truck still has whiteish/grey smoke coming out of tail pipe. I had to replace the drivers side upstream O2 sensor. I bought a Actron OBDII reader and it keeps telling me Mod 18 is not working, any clue what that is? Temp is between 196 and 230. 230 was with the truck parked and running with the AC on. I have posted pictures of all the screens on the OBD reader...pictures were taken in park at idle.
