ENGINE LIGHT FLASHING AFTER PURGE VALVE REPLACEMENT

I have a 2008 Cadillac CTS AWD. My check engine light has been on for a while, and I was told it was because of a faulty purge valve, and that it wasn' t really serious. I finally got around to replacing it (did it myself, but seemed fairly straight forward). I took it out for a drive, and after about 10 minutes, I could feel the car pulse slightly, almost like I was letting off the gas, and the check engine light started blinking, but only for a few seconds. Any idea what could have caused this?

    Hello hannack22,

    I'm sorry to hear about this pulsing concern you're experiencing with your CTS. I understand you are seeking advice from forum members, however, if you are interested in getting an official diagnosis, we would be more than happy to assist in setting up an appointment at your dealership to have this addressed. If interested, please send us a private message at your earliest convenience.

    Sincerely,

  • I took it in, and it came up with P0014 and P0024, which show as both cam shaft issues. Not sure why this would happen after replacing a purge valve.
