Hello,
Ive had my LS now for almost 3 years now and the only problems Ive had were with the suspension (axle, and several bushings) due to the previous owner putting the incorrect rim and tire size.

Recently within the last few months, the car hesitates while im in motion driving but trying to accelerate. It also has a very very low idle, and when im stopped at a light I have to put it in neutral to raise the idle to enough to where it doesnt die.

Yesterday I noticed it was running especially rough. This morning I started it and it was running really rough while idling in park. Its making a muffled grinding noise as soon as I start it. It is the worst while I am stopped. It drives very rough but it is the worst while in neutral. It also died twice today while I was in park with it running.

Any advice at all would help a lot!

 

First off, welcome, always good to see more people here in AZ joining up.

Second. This grinding noise. Does it sound like its coming from the engine, or the transmission?

 

How many miles on it?

 

Check engine light on?
