To preface this question I’ll state that I have had a few exhaust line issues on my Nissan Sentra ( holes, 2 failed converters ) all of which have been fixed and have held up very well. I had a bit of bad luck also while drving on the highway. I ran over a peice of sharp metal that tore through my oil pan. I had the car immediately towed though and the pan was replaced.
With all this in my mind I now have a stuttering engine that fails to start frequently. Whats up?
