bro,You are right there are tones of reason for misfire, all the work shop you go will tell you to do this and that but not able to tell exactly what is the problem becasue they are lazy to put in the dianostic to check the problem. They think they are GOD can see what is the problem without plug in the dianostic. Doctor also need to do blood test to find out the sickness right.
Recently bought a unit of OBDII dianostic from US, plug in my car it show up 5 error code on my car even it is drivng ok every day except a bit of detoning sound. Check all the code identify as fuel too lean on bank 1 and too rich on bank 2. All may related to air fuel mixture.
Search the net identify problem might be the MAF sensor dirty. I went to buy a can spray of MAF cleaner to clean the sensor.
Now the work better and more fuel efficient, detoning sound gone.
How much did you buy the OBDII dianostic?
