my 600 se hasn't been running for the last two weeks cause of (what I thought were only) ignition problems. It had a rough idle and deeper exhaust note you could feel a little through the car.
So first things first, I swapped all 12 spark plugs and the car ran fine for a couple of days.
After those days the car started to run worse again when I started it up, when I ran it for a little I even noticed misfires when driving. It also smelled terrible from the exhaust and it gave alot of smoke, especially when revving up.
So I was directly thinking about caps and rotors, bought 2 new caps which finally came in the mail today and cleaned both rotors.
Now here's the weird part, the car has a steady rpm but the engine still is a little shaky (too shaky for a m120) when you put your hand on it or a coin.
It still has a terrible smell and the exhaust smokes alot. When I rev it it gets worse.
So my theory right now is dirty o2 sensors from all the unburned gass.
What do you guys think?
