Rough idle after belt replacement
Hello all,
About a month ago my belt snapped. Apparently the pulley had seized and eventually the belt snapped. Had the tow truck take it to their shop which fortunately was right down the street from my house. Took them about 2 weeks to replace belt. Got it back but the check engine light came on. Took it back and they replaced a sensor. No more check engine light, however it's been idling very rough since. I haven't put my analyzer in to check for codes yet. What should my idle RPM's be? Any help would be appreciated.

Codes will give you a hint as to the next step that is required. What is the maintenance history of this car? Time to roll up the sleeves and give her a good going-through?

I'll check to see if there are any codes later on today. Drove it for the first time after about 2 weeks and at first it was really rough but after driving awhile it wasn't as rough. Still not as smooth as it was though
