today when i was leaving work i started my car and it was sputtering almost hesitating with low idle ( talking about near the 0 mark) and my car was shaking and when i looked at the under the hood everything sounds fine but when i looked at my muffler it was like ( ok dont make fun of me for this) it was making a noise like putt putt putt putt and no a smooth sound. BUt yeah and when i was driving and i hit a stop sign it felt like it wanted to cutt off . When i went on the freeway i reached 50 miles and the check engine light came on and then i got off the freeway a couple of miles and the car was fine then when i got to my house i turned off the engine and then turned it back on real quick, to my supprise the check engine light came off.I took it arround the block and everything was normal and also on the freeway again normal???????
