RE: intermittant rough idle on start 1994 E420

Redwood -

It did it again this AM. This time, in an attempt to test your fuel pump theory, I turned it off and started it about 3 times. No change.

Looks like you gotta put in your 2 min. of running on 6 cylinders. Interestingly enough it always feels like 2 or more cylinders not operating. If it were one you probably would barely notice it. If you open the hood you can see the engine slightly rocking until it goes away.

So, could you fill me in a bit more on where these fuel pumps might be located? How much they might cost? Also, if one of them fails entirely then what happens? you get half an engine? [XX(]

Getting codes checked - If my mechanic cleared the codes would they still be in the memory because the check engine light is off right now. Dont want to drop $120.00 just to have the dealer tell me there arent any codes.

Wiring harness stuff. Where is a good source for this part cheap... I can hear them sharpening the wallet hooks now.

Thanks
