I have a 2003 Tacoma with the 5vz-fe v6 with 175k on it. Threw multiple misfire and cylinder 3 and 5 misfire codes. I had just purchased the truck so I replaced all spark plugs(Denso), ignition coils(Denso), ignition wires(Denso), cleaned MAF sensor and throttle body, and installed new air filter. Check engine light came on about 200 miles later with the same codes. I then proceeded to replace cylinders 3 and 5 fuel injectors. Check engine light just came back with the same codes. I’m not experiencing any loss of power or hesitation through acceleration that I can tell. Has a shake at idle but goes away when given some fuel. Vacuum lines seem fine. I’m about out of ideas. Any advice would be appreciated.
