1998 4.6 missfire codes
I have started to get missfire codes on my truck, first was a cyl 5 and then on cyl 4.
I did get the flashing CEL and it reset once I shut off the engine and restarted.
Truck has 207K miles and is a manual, the flashing CEL was in 5th gear and low load.
This may be related, I have a coolant leak I can not find.
The smell of raw coolant is around the truck and no smoke out the exhaust or any trace of it in the engine oil.
I do have 2 new coil packs and wires along with plugs.
What has me even more puzzled is that cyl 5 and 4 are coming up, different side of the engine.
Any help is appreciated.
