Hello. I have a 06 pontiac g6 2.4 le5. recently its starting shifting real hard out of first into second and check enginr came on. We plugged it in came up cam position sensor #2. So i just replaced both sensors incase and we deleted and reset the computer. It came back within a half mile. Ive seen some people post on google its a catilatic converter issue but before trying that id ask if anyone has any ideas? Im trying to fix it without GM doing it. Ive kept excellent maintenance and have done all repairs immediately. Its at 75454 miles. Runs awesome except this so far. Please help!
