Ok I love this car. Well for about a month now. My car as been misfiring. Did everything related to a tune-up. I replaced the cam sensor. And replacing the crankshaft positioning sensor today. Well I took it out for a spin yesterday. Got up to 80 for a lil bit. Then starts to hesitate down to 70 then 60. And so on til it got to 10 then dies out. And also engine power isn't the same. Starts then dies out again. And the whole time check engine light is blinking. Has anyone had this problem? I'm wondering if crank sensor will even help it. But I don't know anymore. Please help and thank u.
