Car starting cutting off after every complete stop. I was told car needed tune-up. Got tune up and car started misfiring and check engine light was blinking along with another on. I think it is epc or something like that. Took car to auto computer read that I needed a camshaft position censor. Got that put on and still the same problems.

Hi and thanks for using 2CarPros.

A misfire can be caused by many things. First, if the light is flashing, I wouldn't recommend driving it until it's fixed because it could damage the catalytic converter.

Here is a link I need you to look through. It discusses misfires and the most common common causes.

As I'm sure you saw in the links, there are many things that can cause a misfire. Understand if there isn't correct timing correlations between the crankshaft and camshaft position sensor, it will cause problems. That can even be a result of a timing belt issue. If you have the specific trouble codes that were retrieved, it would help me to point you in the right direction. Also, let me know if the crankshaft position sensor was replaced.

Take care,
Joe
