View Full Version : 01 Sable ls premium emissions problem

I have an 01 Sable LS Premium with 42k. Showroom condition. However, now my son says that when the a/c is on, there is a miss in the engine. It does have a miss when you are stopped, but it's fine once you start moving. Could this be the oxygen sensor? MY email is: intimadator3824@hotmail.com. Thanks.

Most likely its not the O2 sensor. Check to see if you have a vacuum leak, bad injector or you could actually have a mechnical problem with the engine itself. The first thing you should do is check to see if there are any trouble codes stored in the PCM.
