2010 GMC Canyon, rattling sound during 3rd, 4th, 5th gear
sounds coming from the lower engine i assume, since i can only hear it when im driving 30+ mph. anybody got any clue what it can be. my truck is still under warranty but i don't want to go in and them to say "nothings wrong with this truck" because i look like a sap that will fall for it.
truck only has 3100 miles on it, and its a 4 cylinder manual transmission. i also noticed the rpms on start up dip down to 500 to 700 from 1.1k, is that normal? and one last thing, when i reverse and press in the clutch to throw it into first gear, my engine 80% of the time almost stalls. another weird thing i noticed.
can anyone help me out?
