did he get the firing order correct when he plugged in the COP's?

5w20 oil only. anything thicker can run the risk of engine damage.




also, Ford does not, nor will they ever give out additives. There are too many sensors that can be damaged. Your shop sounds quite incompetent to me.



have the guy check that spark plugs #7 and #8 are tight and not broken, check that all the sensors are properly connected.


he might have also forgotten to connect the CMCC on the back of the intake...or didn't connect the vacuum lines back there.
