I have a 2001 Sebring 2.7 auto,replaced the water pump, Timing chain(since I was there), tentioner and plugs. The car runs great and does not overheat but has an intermitent misfire. the check engine lite is not on and when I connected the code reader it said that it could not connect to vehicle. I tried two different code readers and both types of cables, still will not read.

Never had a code reader not connect so I am at a loss.
