Just swapped the cam from a working car. Guess I’ll look further into camYou have a cam sensor issue. Did you check the wheel? What kind of cap did you swap? If it’s a Casper’s, get rid of it.
Make sure the cam sensor wheel is not moving around. Make sure the tab on the wheel is not broke. Any play at all is a problem. Focus close on the cam sensor..
And put a stock cap back on it...
