Advice?
My car is a 2000 E55, 42,000 miles. Yesterday while pulling onto the freeway I floored her and cylinders started dropping, I slowed pulled to the side and the engine was running on half the cylinders looping and chugging. Check Engine light came on flashed a couple of times then went steady. Once I turned the engine off and back on again it ran fine.....until I floored it, same result. Codes were P300, 0306,0303,0304. Besides the low mileage I'm going to rule out cats due to missing codes on different banks. Gas cap is on, plug wires look good. Any suggestions?

Yes, basically I reset the ECU cleared all faults. Drove the car and it did the same exact thing, this time however it just gave me a P0306 fault. I can work with one misfire. So I replaced the plug wires on cylinder #6 (that's the P0306 fault misfire on cylinder 6) that solved the problem, I couldn't get it to repeat. Next step was going to be swap coil pack with cylinder 1, but no need.

I would advise you check for collapsed motor mounts - collapsed mounts will lead to wiring/misfires - well over 98%+ of W210 spark plug wiring is alive and well - and never has had to be touched regardless of mileage.
With low mileage E55 such as yours - I have recommend a maintenance list in the "other" forum - based on what really goes.

We'll see, just drove from Tacoma to Seattle and back, she runs perfect. Before this, it was happening almost at will after the car warmed up and it was floored. A bad wire could in fact effect other cylinders, remove a wire then drive your car and run the codes, that might make a believer out of you. My hypothisis, the secondary spark didn't have the continuity it needed at full throttle so the ECU cut that cylinder to keep from damaging the engine, this intern effected the other cylinders, which caused the rough idling. Restarting the car, everything went back to normal, until I floored it resulting in the same condition, I did however, pull over right away and restarted the vehicle, that could explain no other codes. None the less, if it does come back I will report back and let everyone know of the progress. Hopefully it will guide others in the right direction.

Ok I see. Last time I had my car scanned at the dealer they told me is was misfiring. So I replaced plugs,wires,coils and maf sensor. I hope I fixed the problem, I have no way of knowing. The car runs the same , its seems like I lost some power since when I first bought the car. Its like it has slower acceleration.

For the slower acceleration have you reset the transmission ECU and vehicle ECU? To reset the vehicle ECU disconnect the battery for like 10 minutes, for transmission look at the vid below, I'd try the tranny reset first, it might surprise you.

The dealer recommended changing the wires. I went ahead and replaced all 12 wires. I initially went to dealer for a rough idle issue, it seems like the car had a slight shake to it. They said it was misfiring mainly on cyl 3 and 5 but on others too. They was also a code for the IAT sensor.
So I went ahead and replaced everything , plugs wires, coils and the sensor. The car ran better with more mpg. While it still produces good power I feel hesitation sometimes and it idles low when in drive gear with brake on it idles like at 600 rpm. So I don't know.....maybe its still misfiring maybe its not .That's why I inspected the sparkplugs. Maybe for Christmas ill get that Mb star tool ive always wanted
