M157 Misfire on Cylinders 1,3,5,7 after resonator delete
Hello did a resonator delete with straight pipes yesterday and pushed my 15 cls63s to 130mph a few times last night. All of the sudden the car looses its power, vibrates and shakes alot, and sounds weird under acceleration/throttle. i get a check engine light on for a misfire on cylinders 1,3,5,7. Cleared the codes and the problem seems to have gone away. Any ideas on why this could be happening or what i can do to prevent or fix this from happening again? Could the resonator delete be causing this or is it just a coincidence that this happened on the same day that i got the resonator delete done. Car only has 35,200 miles on the clock and is otherwise completely stock
Thanks

And change your coils ... these are weak links on the m157 ignition system
when the turbos heat up they can flesh out weak coils ... hence possibly why you're misfiring after hard runs
also bad fuel.....

any recommendations for spark plugs and coils? Not sure if colder plugs are best in my situation as I am running a stock set up. I get a full tank of 93 octane gas from Bp every week(sometimes twice a week),

you have the typical noisy lifters however you have an additional metallic rattle that doesn't sound too good but I have no idea without hearing right next to the car as these phone mics are weird
