I had my new fuel filter installed at the stealer about a month ago. Surging at idle has been a problem ever since. It did surge a little here and there at times with the old style filter and could be cleared up with a little additive, but now in does it constantly. It seems to me that the new filter may be a little more restrictive since it all of the sudden got worse when it was installed. I also want to mension that the Fuel Pressure Regulator and injectors were replaced @ 90k. I currently have 119k. Anybody have these symptoms after your new fuel filter install? Any ideas what my problem could be?

moving to LB7 section, I doubt you have 119k on an LBZ already. ;-)

oops!

Take out your edge and see if it makes a difference. That is what my problem was. I contacted the edge company and they sent me a new replacement. Ran good since.

JeffAlready tried this and still ran the same. Thanks though!:)

Bring it back to the dealer that changed the filter and get it documented before it's too late.
