So this infamous multiple misfire crap has me on the verge of getting rid of the car. Car has 167k miles on it, so still "has time" and what's weird is when I cruise, I get NO misfires. My mechanic connected his "expensive" OBD interface and saw too there are absolutely no misfires when cruising.
So yeah, I did everything below and STILL have the misfire, mostly while accelerating and at idle...
Made sure the replacements were all OEM parts too, smh.
Spark plugs
Coils
PCV valve
Intake hose (had a small crack)
MAF sensor
Idle Control Valve
EGR Valve
Timing belt change with water pump, tensioner, etc.
Valve adjustment
Fuel Injectors
Also,
Cleaned EGR ports and throttle body
Did seafoam through vacuum hose and gas (separately)
Mechanic checked the pressure of the fuel pump and he said it was fine.
Misfire for cylinders 1, 2, 4, 6 is what I normally get. Even though they are all new plugs and coils, still tried changing it around, same misfire codes.
I've legit searched through this whole forum, but no luck 😑
