07 losing power in low gear acceleration
My 07 LTZ is losing power in low gear as I lightly press the accelerator. It gets to the pint that the whole truck will vibrate like it is going over rumble strips. As soon as I let off the gas it goes away. Or if it hits the next higher gear the chattering goes away. I have 100.000 miles on truck and just did a major tune up. Plugs,wires, fuel filter. This problem was also happening before tune up. That was one of the reasons I changed out plugs and wires. Any suggestions?,
Thanks
Thanks

I had very similiar problem I did not notice loss of power but I had all other symptoms you describe.
My issue was a bad u-joint on the drive shaft. The dealer said it was frozen and not moving freely.
Mine was even covered under the powertrain warranty.
Good Luck

I will have the dealer check it out this week. Im about 300 miles over powertrain warranty so if that is the problem I may have a warranty issue.
Thanks for the help.
