The 420 is noted for random misfires p0300 most notably for the spark plug connectors.Have you recently washed the engine or ran through a big puddle of water?
Check all plug connectors and spray a shot of wd40 down each spark plug recess to dry any moisture and then see if the erased code comes back.

@OHLORD
Now that you mentioned it there was just a big rain storm we had Tuesday and thats the day i got it and i did go thru big puddle of water so that migh of contributed to the error. I reset the code with my scanner and its been two days so far so good so hopefully that was the problem.

I have P0308 and P0300 on 97 E420
Check my post, I have misfire on cylinder 8 and then I got p0300. I am putting new plugs, new coil on cylinder 8 and waiting to find out if I should replace spark plug connectors. www.Shopstopanddrive.com best price for ign. coil other items.

$60 more
for an mass air sensor at that link and while the coil is the same price the 10% added for shipping when autohausaz.com ships for free over $50 orders.$8 more for an evap temp sensor plus $6.50 shipping for a less than 1ounce part
it really pays to shop around some.How is their customer service?and should not the link read stopshop not shopstop![rolf](https://mbworld.org/forums/images/smilies/rofl.gif)
and drive.I always find it helpful to stop before getting out to shop![thumbs](https://mbworld.org/forums/images/smilies/thumbsup.gif)
