3. Stick Shift or Automatic Transmission : AT
4. Strange sounds or smells :see below
5. Fluid leaks : see below
6. Past repair history :
I bought the car not to long ago its been only a couple of months. When i first got the car the first problem appeared when I looked at my coolant in the overflow coolant tank and realised that the coolant appeared murky very sludgy brown and disgusting . When the car was given to me i was told that it had a new radiator, water pump, and etc and had put a shitload of stopleak in the coolant "to make it run nice". However I think they put the stop leak in and all of the repairs (which in return became obsolete through rusting) they did because they could not be smart and realise there was a coolant leak in one of the hoses. As soon as i figured this out i replaced the hose ( Upper ). Since then I have flushed the car several times and have even taken the over flow tank out and scrapped the inside walls of it until it looks brand new. From the rust that has collected in the coolant system from the large amounts of stop leak and completely rusted out heater core (the heat in my car has never worked ) everytime i flush it a month later the coolant starts to again turn brown. Though I dont think that this problem has anything to do with the problem occuring now, you ask the car's history. Then the alternator needed replaced. Recently after this the stalling problem began. There is no common gesture of what you are doing with the car when it stalls out. It just does whenever it wants. You will be driving and then all the sudden boom the car is off , no sounds, tinks, or jerking. I ran a scanner on it and the code said it to be the mass air flow sensor. The code read either mass air flow sensor is dirty, defective, or a misfire condition. Originally the problem was very suddle, it would only happen once in a while and the car would start up 10 minutes after it stalled out. However now it has been getting increasingly worse, to the point where my car would not start after it stalled out for 8 hours. It is doing it much more frequently too. As a cheap way to see if it would fix i replaced the spark plugs ( NGK ) and premium wires. Even though the car ran smoother, the stalling would persist. Before I could afford the mass air flow sensor however, there was another vital thing wrong with my car. A nasty, marbles in drier (eventually leading worse and worse) sound came popping from the engine in which i discovered the idler pulley assembly was ceased. I replaced that pronto. Yesterday I finally saved up enough money to get a remanufactured mass air flow sensor from advanced auto parts, put it in my car, drove it down the street, and boom. Stalls out again. I had to leave the car there over night. The car is scarey to drive, no mechanic can tell me what the problem could be. It has been suggested to me to check my ignition module and coil packs. However, I am 19 years old and am out on my own and make 150 bucks a week ( so as you must understand this car has been stressing me out very much ). I do not have the room to play around and keep adding parts that are not fixing the problem. If someone could please, please help me try and figure out what is wrong with my car I would be so ever grateful. Also so just so you know I also have full cat back flow masters and a k&N short custom intake on it. Thankyou - Melissa
