On the computer it said: EGR Flow Malfunction and Knock Sensor 1 Limit Malfunction.
I need help about where they both are located, what to do, where to look..online or store, and anything else about it.

Answer
Hi George,

Replace or remove and clean the EGR valve which should be located on the back of the intake manifold and will probably have a stainless steel line coming out of it and connecting to the exhaust manifold as well as a vacuum line and in your case, a wire harness which 'should' have three wires. The DTC's you're getting are both pointing to the EGR.

So I don't get myself into any hot water, I need to tell you that since the EGR valve is a sensitive and calibrated emissions device, I can only advise you to seek a reputable, local repair facility to perform the repair. Sorry. The advice given above should be used for reference purposes only and is not intended to direct you, yourself, to attempt emissions component repair.

Good luck.

Looking for a reputable service technician? My advice on finding a good technician is: Steer clear of the dealership and 'chain' stores like Firestone, Sears, Pep Boys, Monro Muffler/Brake, Midas, etc. as they usually only employ ONE ASE Certified Tech just so they can say they do and chances are, that guy is the asst. manager or manager and is not in the store to diagnose/repair vehicles anyway. Find a service location in the link below or get some names out of the yellow-pages and do a drive-by. Garages that employ ASE Certified Technicians will be marked with the 'Blue-Seal' insignia. If unsure about whether a place employs Certified Techs, just ask to see their credentials. ALL ASE Certified Technicians will be PROUD to show and display their certificate(s).

Thanks for the question, I hope this information was helpful to you.
