I am dealing with Cylinder Misfire p0300/P0302/P0304 codes on my Toyota MR2 Spyder and trying to get to the bottom of the issue.
Here is what I have tried so far:
- Changed all 4 Spark plugs
- Changed all 4 Ignition Coils
- Checked wiring that goes into ignition coil
- Added fuel system cleaner to the gas
So far no success.
Can someone point out what could be causing the problem, what additional tests I can perform to narrow down what part is likely causing the issue?
