Volvo Repair: Volvo s60 2001:Check Engine, volvo s60, co workers

Question
I got the check engine light on and got the codes read to be p0128. Wondering which is the best place I can get this repaired in IL.

Answer
  Radha, how would I know? I do not live there. Ask your friends, neighbors, relatives and co-workers who they use and trust. Make sure the place is clean and well organized. The cheapest place is never the best. Ask if they guarentee their diagnosis and repairs. Anything less than a one year I would steer clear of.
  I hope this helps.
