I have a 2018 Honda fit EX recently had all dash lights come on I have changed spark plugs coils air filter oil change O2 sensor fuel injectors a seal and I just recently got a PCV valve and it's still having problems called Honda manufacturer called Honda dealership I guess there's a recall on the fuel pump but it won't be here for a few months just so frustrated with all the work that I put into it oh yeah the carbon had that cleaned up as well when we had it tore apart doing the fuel injectors I'm so over this car and very frustrated any suggestions still waiting for the new fuel pump to come in from Honda to fix it but it's still throwing misfires

 

hmmm...it sounds like you have done a thorough job..do we have a Crank position sensor ?

does it seem like its misfiring ?

 

Yup we checked that now we think it's the Cadillac converter from the carbon buildup.

 

Cadillac converter - I think Johnny Cash sang about that.
