Fuel filter, air filter, MAF sensor, spark plugs and wires,
cleaned injectors, replaced cat conv (junk), hesitates only when fully warmed up in any gear when rpms are at about 1500. Coils test good. Codes showed misfire in cyl 1 and 5. Fuel pump repl 15K miles ago.
Hasn't given me any trouble until now (except for fuel pump. Have owned for 5 years/50K miles. Oil and coolant good. Cond made worse when air cond on and have passengers (high load/low rpms). No symptoms when engine cold. Bad injector? Bad ignition module? O2 sensors?
have the same problem?
