Having probs with my caddy running very rough. It is like it has a mind of it's own. sometimes I can get in it and it runs like a different car. I can be sitting at a red light and the engine just races up and down and it sounds like a truck. also my electric trunk pull down motor works when it wants. can some help. Thanks in advance

Please do a search on the rough running..... This is VERY VERY common to the 4.9, and there are plenty of posts covering stuff about it......

The trunk pull down motor..... Usually stuff gets in there and it needs to be cleaned...... Do a search on that also, this is also quite common.......

Probably the throttle position sensor....Not a big deal. Check your codes.
