Engine is a GDI engine. Sprayed intake valve cleaner through the throttle body like it said to do on the can. Followed all directions on can. Came back out to start it up and it started and idled perfect but I could not get it to rev above 2000 rpm's. Tried taking it for a drive and still wouldn't go above 2000 rpm's and started to shut off when it maxed out. Came back home thought it might have been the catalytic converter took the exhaust manifold off (catalytic converter is welded to exhaust manifold) started engine and still would not rev passed 2,000 rpm's. What else can I try to get this thing to work right?

Hello,

Is your Malfunction Indicator Lamp (MIL) or "check engine" lamp illuminated?

Thanks,

Yes it is. I am going to the auto parts store today to rent a scan tool to see what code pulls. Would I need to put everything back on before hooking up the scanner?

Hello again,

This Direct Trouble Code (DTC) is for a bad knock sensor and is usually due to a problem in the wiring to the sensor. I have included in the diagrams down below the factory diagnostic troubleshooting guide for this DTC for your vehicle. I have also included guides for how to check an electrical connector in an automotive electrical circuit as well as how to check for shorts to power, shorts to ground, and opens in an automotive electrical circuit as well. You will need to use a Digital Multi Meter (DMM) so I have included a link below for you if you are not familiar with how to use one.

Please go through the guides below and get back to us with what you are able to find out.

Thanks,
Alex
