ok, so i developed this code tonight, and i really believe something is not happy, because along with the code the car is really not running very happily. so i hooked up the autoenginuity scanner and got that code, which is a cylinder #4 misfire. well, my question, which cylinder on our engine is #4? as i wanna check and see is something is just lose, or something simple. but after searching 6tech and here, i cannot find anything. thanks for you help!!
