Fing P0420 again. any ideas?
Ok so over the past 8 months.
Cat was bad replaced it, front 02 was replaced, rear 02 was reading bad changed it.
Still getting the code ever 2 months or so.
I'm out of ideas and do not have time to check or work on the car anymore for about a month. (buying house)
I've heard the coil packs could be going bad but the car is running smooth as ever. How do I check the coil packs?
Do I check for exhaust leaks?
Could a dirty (caked with oil and grime) crank sensor cause something to be off?
I;m frustrated.
