i have a 2003 s10 code shows misfire on number 4 cylinder it wont fire at all
code shows po304 cylinder misfire new plugs wire are good cylinder pressure is good fuel injectors show good but there is no fire at number four.
Remove the spark plug on #4. What does it look like? If you have spark, fuel, and compression it has to be firing. Unless the spark plug is fouled. HTH. -Jim
Swap #4 plug with another cylinder to see if miss moves.
