My check engine light will go off and on

That sounds like one of those intermittent problems that's hard to pin down. If your code indicates cam position sensor, I would just go ahead and replace it. They have been known to heat up and cut out, or set a code, then come back on. They're usually not too hard to reach and I buy them on Ebay for $10. Some people say that's Chinese junk but they all come from China repackaged. So yes, just replace it and have peace of mind for $10.

Done that 3 times with the same result. Engine light comes on randomly and goes off randomly. Car will occasionally shut down while driving, even at 50mph!! Why I'm just thinking of just biting the bullet and getting the computer replaced


what is the 4 digit code?

It's the cam sensor code. Think it's p0340. Have to scan it again
