Hey guys I have a 1996 nissan 200sx se-r. It has a 2.0 engine in it with 168,000 miles on it. What happens is the car will not idle smoothly, it will idle up and down. I live up north and when it gets cold the car will run fine and then it will bog down. It will bog down when you get on the gas, and also driving it on the highway. Also my car is a manual and when I shift into a higher gear causing the rpms to go from high to low, it will bog down also. When the temperature outside get a little warmer, the car will run better, but it will still bog down. At times it will get so bad where it seems like I have a cylinder out, but this happens only when it is like 0 degrees. There is no check engine light on either. I have been told to check the distributor, fuel pump, but I personally think it is the mass air flow sensor going bad. Please help this car is starting to drive me insane!
