2002 L300, P0304 help please!!
Hello there, I have a 2002 L300, 3.0 ltr. The service engine light came on, it is code P0304, cylinder 4 misfire. I replaced the spark plug in 4, nothing, new coil, nothing, switched the #4 #2 fuel injector, nothing, checked compression on #4 it was 195 or so. I am at a loss of what this may be. Please anyones help or suggestions would be greatly appreciated!!!! Thanks in advance!!

Check and make sure you have injector pulse on #4. Are you sure you are getting spark to that cylinder? Only other thing I can think of is maybe the boot between the coil and plug may be damaged.
