I recently changed my plugs to nkgs and it made my car run rough .

What is your question?

at the same time i replaced the front o2 sensor because because it was throwing the code for it.now it is throwing the code for a camshaft pasition sensor . Do you think i should put the cheap plugs back in .I know you list several things it could be for that code . but do you think it could be the plugs since thats what i changed first and made it run rough.
