Hi again. I just read your response to the first post. If there is a warning light on, you need to have the computer scanned to identify where the problem is coming from. Many parts stores will do it for free. However, not all of them have a good enough scanner to read trans codes.

Sorry im new to using these car forums

No problem! I thought it was regarding the same vehicle. My last response is what I recommend. There are so many sensors, solenoids. That can go bad, without scanning the computer, it becomes a guessing game. Therefore, have it scanned. It should point you to the problem.

No codes popped up

If no codes came up, it needs to be driven / checked by a tech. Anything I would say from this point would be a guess.

Think the filter is clogged

Black smoke usually indicates a rich fuel mixture. Check to make sure the fuel pressure regulator is working properly.

Do you know where tht is located on the car and I'm getting extremely low mpgs like 5miles to the gallon
