Thanks for replying. I started the car this morning,it ran for 10 mins.,then died. right before it died,the rpms were going up and down,like it was trying to keep itself running.I noticed some black fluid that came out of the tailpipe on the floor and wall of my garage that smells like gas,and the car would'nt start.sometimes it will run fine,then it will start to sputter and spit black smoke.I believe you are right about the tcs not being a factor,but this is my wifes car,and Ive had a bit of trouble with it as of late.I just replaced the head gaskets about a month ago,and now this.
