Replying to: frichards62 (Oct 28, 2008 7:37 am) it could be the serpentine belt idler pully. have that checked.
#9 of 11 2005 Chevy Trailblazer losing power.. by davedoran1975 Sep 25, 2009 (4:50 am)
Driving in the first few gears, it seems the engine seems fine. In the last gear though, when speeds are over 45 miles per hour, it seems as though the truck is just dying. I can be at the same speed of 50 MPH, but I watch as the RPM gauge starts to drop. It does this a lot especially if there is stress on the vehicle (i.e up hills) Sometimes when driving at that high speed and start to go up a small incline, the engine will start to slow down and the rpm's will bounce up and down like it's losing power I had a tune up and they replaced the spark plugs, i had a engine flush, etc. What else could it be?

Replying to: frichards62 (Oct 28, 2008 7:37 am) recently had the same issue... LOUD whining noise. Took it to my local mechanic, he replaced the idler pulley - eliminated the problem entirely. ($135 repair). Good Luck!
