Default Re: misfire p3000 after catalytic converter replace
No all welding was done off the truck.

I replaced the passengers side cat about 8months ago.

I started have the random misfire code after replacing the drivers side a few weeks ago.

I only had the code for a bad cat on the drivers side then after replacing It started with the random misfire code.

Is there a way to test the individual coils ? Maybe with an ohm meter ? what would be the number range I,m looking for.
Thanks
