Last week I had someone to put an alternator in my car. He took off the front section (grill and radiator)and installed it from the top. Afterwhich, I noticed some lights that were on my dash board so I took it to auto zone top be placed on the machine. the code on the machine stated that the PCM need to be re- programmed. I took it to someone at the dealership (that did me a favor or so I thought) to reprogram the PCM. While entering the codes in the diagnostic machine he noticed a vacuum line that was loose. He went and got a line and re-connected it. After I left the car began to smoke terribly form the tailpipe. neither the anti freeze level nor oil level is low.
My car has 130000 miles.
