When i drove my car today, I noticed a huge difference in its performance. When i would acccelerate to the point where the boost would kick in (1990 SC) It seems like the car would bog down, and even lose power. I can slowly gain momentum, but I cannot accelerate quickly, and sometimes the car will even die at idle. My dad suggested that it could be the map sensor, but I dont know what else could cause it. Thank you in advance for any suggestions and comments.
