    LLY: Droning noise at low rpm?

    Sometimes when I am sitting at idle, in gear or in park, I have started to notice what sounds and feels like a surge in RPMs or something. It feels as if my engine is pulsing slightly and I can actually feel a difference. I pulled up RPM and desired RPM on my edge insight and I have noticed...

    LBZ air filter issue

    I went to buy an air filter from the parts store today, bought it and tried to put it in, but the filter had a rubber "band" part around the end that goes closest to the MAF sensor, and wouldn't fit like the old air filter (pretty sure the old one is at least 6-8 years old) I googled the part...

    What makes the ECM determine if it wants to test the turbo vanes or not? Does it test periodically or randomly? I was driving to work today (About 5-10 miles) and it seemed like every time I was at a red light or stop sign, I could hear my vanes being tested or at least I could hear the...

    LMM: Thoughts on price?

    http://tallahassee.craigslist.org/cto/5208824408.html Anyone have any thoughts on this posting? I was thinking about possibly trying to buy this and sell my LLY for a new model. I still have about 5500 to pay on my truck, so I would have more to pay for the LMM, but not sure if that is...

    Annoying cosmetic issues

    Has anyone ever dealt with these cosmetic issues? 1. Cleaning the inside of a GM headlight? Can you just take it apart? Or is it not worth the trouble. 2. The bumper piece being off of the metal. It looks like it's going to fall off Sent from my iPhone using Tapatalk

    Duel CP3s or single nodded CP3

    After doing a quick search about modded cp3s, I saw several people post that modded ones seem to fail and they recommend duel cp3s, does this still seem to be true? (The threads were several years old) Would running two stock cp3s be beneficial as opposed to one of Mark at Danville's modded LBZ...
