Good Morning,
Jeep is showing multiple misfires and bogged on me this morning.
The thing is though I've replaced the spark plugs with NGKs and also replaced the ignition coils 1 and 3. The only reason 1 and 3 were replaced because the spring was jacked inside the coil. All the other coils checked out.
Plugged in the OBDII scanner this morning and got P0300 (Multiple Misfire), P0303(Cylinder Misfire 3), P0305 (Cylinder Misfire 5), and P0306 (Cylinder Misfire 6).
*Cylinder 5 just came up this morning.
I re-seated Cylinder ignition coil 3 and it went off for a while and ever since 6 started misfiring it started spreading like a wild fire.
I checked the ignition coil over cylinder 6 and it is fine and so is the spark plug. I'm going to reseat the spark plug once I get home.
Any other suggestions would much appreciated.
Just for clarification the Jeep is a 2003 Jeep Liberty 3.7L Sport.
As far as I understand the diagram for the cylinders goes (looking from the front of the Jeep):
1 4
2 5
3 6
If this isn't correct please let me know.
