OBD code indiates Cyl. #4 misfire.
Wires and sparkplugs replaced at 100k miles for general maintenance. Before misfire was a problem. Lube was wiped on boots at plug and coil for good seal.
Plugs and wires of cyl#4 & #5 swapped but problem did not move to cyl#5.
Fuel pressure measured at 30 psi and should be 39 to 55 psi. Fuel filter replaced but pressure still the same.
Fuel injector replaced on cyl#4. No change.
ECM connector un-plugged and plugged several times to assure good connection.
Where do I go next? :Cry:
Coil, ECM, sensors?
have the same problem?
