I have a 1999 Chrysler Sebring LXI. I had problem passing the emission test to get my tag.

I was told it may be electrical or a fuse. I had a tune up with spark plugs replaced, O2 sensor and the "check engine lights has been on since the repairs. I have basically had the same work repeated with a new starter installed and now the car cuts off when you slow down or come to stop and the check engine light remains on
