Intake coolant leak& PO307,308
I have a 2000 f-150 4.6. yesterday i changed the thermostate because it was stuck open,and i changed the oil and filter.Well to make a long story short. now it runs like crap codes PO307&308 i know these are 7&8 cyl. misfires. Also now i have a coolant leak under the intake manifold.
It ran good prior to doing these things,just didn't have much heat coming out.
Any help or suggestions would be appreciated.Also by the oil filter there is a plug unhooked it is on the same wire harness as the oil pressure sending unit.
It dosn't look like it was hooked up in a long time if ever.Were does this wire go?
