Reoccurring misfire code on cylinder 3. Changed the injector spark plug and swapped the coils from cylinder 3 and 1
Oh it has good compression and I run seafoam
Here’s some ideas
Hook up a spark tester to #3 coil
Hook up a noid light to #3 injector
Please post back with results
What does “good” compression mean? I.e. what is the actual psi on #3? And on the others?
Which engine is in it?
