Soo lastnight on my way home my car started to act like it wanted to die at idle. I just had the plugs changed last weekend. It has a strange rattling noise when accelerating. No power lost or anything. changing the oil now and cleaning the throttle body. Any suggestions or anyone want to check it out. It has 171,xxx miles on it

I'll check that in a few. after cleaning the throttle body and the oil change it idles better but it still sounds like a cummings diesel engine

 

While you're in there, inspect all of the vacuum lines that may have been disturbed while the plugs were being changed.
