    just replaced the fpr on my 2005 lly, in thoughts that would fix it after reading multiple posts of the same idle surge problem. replaced the fpr and it still does it, possibly worse. but i was thinking maybe it needs time to work out kinks since it’s a new regulator, but my hopes aren’t high...

    I just recently bought a 2005 Duramax LLY with 281k miles and I'm having issues with having intermittent starting issues. When I go turn it over on a cold start, nothing happens. Instrument cluster goes blank, no click of the starter solenoid. Nothing. I have a feeling it may be...

    So I'll preface this post by saying I have searched loads of forum posts related to engine noises and the similar variations and have decided that I'm going to make a post. I have read the "read this first before posting" post. While in park or driving with no load there is a noise from...

    I just got back from vacation and had my brakes serviced while I was gone. I also had an issue with the OBD reader not working, so they found the issue (simple fuse) and fixed that.
