I have a 96 pontiac sunfire gt. 2.4 Lt. I have recently had quite a bit of problems with my car. one of the hoses to the transmission broke and all of the transmission fluid leaked out. i replaced two hoses. (the one that was broke and one that looked like it could use being replaced). Before this went down it had always had a check engine light on and when checked, it showed up as a thermostat problem which i kinda ignored until now. So, I changed the thermostat. Now this is what the problem is now. When I drive the car it has a lot of trouble accelerating and idles odd. I somehow got up the courage to take it to an auto parts store down the road. When i finally made it there after a lot of stressful chugging along like a gocart, i had noticed that the thermostat did work. In fact, i guess it worked too well because the temperature guage showed that it was almost in the red even though I had not used any heat or air and it was comfortable outside. When I got the car scanned, it read that the temperature sensor, MAP sensor, the idle sensor, and multiple cylinder misfire. What could be wrong with this car? I replaced the spark plugs and I dont think that the car is running any better. It could just be my imagination but it seems like the engine is making more noise than ever and guzzling gas more. Those two could just be my paranoia. Could these sensors really cause this many problems and if so where are they located and what can I do? Any info will help. Also if anybody has had any problems similar to this what did you do about it? Thank you
