C32 amg misfire on one bank
Have been getting misfires on cylinder 1,2 and 3, this occured 1 second after i floored it, a friend who owns an exact same car as me with the same milleage had his cats fail For him, so we asumed that was the issue, we removed both primary cats and it still missfires, could the secondary cats create this problem aswell? Im drivning the car every now and then to hopefully get a New code, but nothing! Allthough now i cant rev over 2,5k without it misfiring, and after the misfires theres a hade idle, IF i restart it its to normal, and IF i rev it while in neutral it spins like it should?! Pls help, every answer is appreciated

they disentegrate from inside out and cause a misfire, cause they leak air. They connect underneath throttle body

When I punch it - the CEL will blink - it will instantly run pretty shaggy till I pull over, turn it off, then back on again. I have 8 codes - P0303 / P0302 / P0300 / P0422 / P0300 / P0301 / P0300 / P0302. It had what I would call a 'bobble' at stop lights that has been annoying. Would shake the car at the light... otherwise runs pretty good. I experienced the blinking CEL and shaggy run a few weeks back on what I would call 'mild accelleration' not WOT - just a little kick to pass another car. I am able to make it go shaggy and blink CEL at will with WOT.
New plugs and new wires seem to have gotten rid of the 'bobble'. Going now to clear all the codes and see what pops up if anything. I have had the misfire codes for some time now.
I also am wondering if CATs or CAMs or maybe fixed it with new plug wires (a week ago - not driven it much since).
More info..
4 Codes / 8 Codes? What does the READY mean?
This morning I took it out after the above post... not so sure my 'bobble' is gone... seems better but... I cleared the 8 codes from above.
Here is what I got after two runs on the freeway - the first was good and solid - the second popped the Blinking CEL and then went to a solid CEL. It did not go instantly shaggy requiring me to pull over. I was close to home and seemed to run fine. Got back and these are the codes now. I just cleared the codes before I took it out.
Also... could any of this be caused by an intercooler leak? It used to have the occasional drink of coolant. Now I have not added coolant in probably a year or two.
Thanks for the help.
