Arthur,

when driving my e320, it still surges, but as I go faster the surges get smaller. at 60 MPH you can still feel minut rapid surges. When I slow down, I have to throttle it down so the system does not over gas, causing me to shut the car off because the car goes into a fit. My gas mileage has plummetted.
I will go out and get the codes off of it in a little bit, but I know the last time I cleared out all the code and let it sit, I got code 5 off of pin 8. This is when I did it at idle.

Gary
