SoCaLBaMF Posted February 14, 2013 Report Share Posted February 14, 2013 Mine did that when I turned on the A/C but sorted itself out after a while. Took it to a dealer and they had no clue what it was. 2004 Bagged Trailblazer (4)18" Sundown Nsv3s (4) Taramps HD10000s, Taramps DSP3000, Lanzar opti 250x2, AB 100x4 (2)DC power SP 270s, (14)XS Power d3100s, (1)d6500 Link to comment Share on other sites More sharing options...

WhiteTB Posted February 14, 2013 Report Share Posted February 14, 2013 He said the problem occured after he cleaned it. Guess i should read the whole post first. Your issue sounds like the throttle body issue. Id go back and make sure everything was put back right. Did you disconnect the battery or pull the fuse to reset the pcm? Sign up for gmtnation.com and ask those guys there. They are very helpful Team DOA Team gg Link to comment Share on other sites More sharing options...
