cel came on tonight on my way to work. autozone dude tells me it is code p0304 and then tells me it is the camshaft position senor circuit fault. only proble is that code p0304=misfire detected cylinder 4 and p0340=camshaft position sensor circuit fault. the car runs fine as i commute 100 miles to work. i am going back to autozone and look at the code for myself in the morning. has anyone had a p0340 and what does this mean exactly?
