2002 Grand Cherokee Laredo random multiples misfires on all 6 cylinders after warms up

Asked by Randy Dec 02, 2016 at 04:58 AM about the 2002 Jeep Grand Cherokee Laredo 4WD

Question type: Maintenance & Repair

My problem started out no spark.  I changed the cam sensor, then crank
sensor.  I got it to run but check engine light came on and said misfires on
coil A and B.  I replaced the coil pack and spark plugs and still got the same
problem after Suv warmed up it misfires and had no power.  I then
replaced the whole exhaust because I was told the cats were plugged.  
That got rid of the coils issues but now it runs great when it is cold and after
it warms up to running temps the check engine lights come on and codes
for, random multiples misfires  and misfires on all 6 cylinders.  seems like
when something must be getting hot and causing these errors.  Can you
help me?
