Okay so I have a problem with a code p0300 which i recently found out that cylinder #1#3#5#7 is misfiring but cylinder #2#4#6#8 is firing with no problems and can’t seem to find the problem. I replaced the spark plugs and recently just replaced the lifters and rocker arms but the spark plug change didn’t seem to do anything, both the coils and fuel injectors are getting power but it still seems to Misfire. I’m alittle lost on this one and can’t seem to find a answer’s anywhere on the web. even when I disconnect the coil and injectors one by one on the cylinder that are misfiring nothing seems to change but the cylinders that are not misfiring when I disconnect anything, there is a change of idle which I assumed those cylinder are firing correctly. any help is appreciated thanks.
