So my car is over 10 years old and its basically starting to fall apart. I just replaced my battery, alternator, took care of some leaks and my car powers on and runs and gets me from point A to B. Every now and then when I pull up to a stop light or sign or down shift around a corner my car seems to bog a little and my RPMs go all the way down to like 2 or 300. Once and a while at a stop light my car will die. but it will start right back up. This has been going on now for almost 2 months. If anyone can help or has any ideas let me know. I also just replaced my TPS.
