Today I was out joy rideing and noticed my check engine light was on...big surprise. So I decided it would be a good idea to check my error codes. Never done it before but i am familiar with the process (at least i thought). I connected the te1 to e1 terminals and started my car and noticed that the engine light was on but no blink then after about 10seconds after my car started sputtering badly. I dont know whats going on, if someone could shine some light on this for me I would greatly appreciate it. Sorry if this has been covered.
