AM Noise problem

Ok guys, HELP.............On Am only I have really bad noise, only after the car warms up, and goes into closed loop..Does not do it when it is cold...If I am going steady it is terrible, if I let up on the gas the problem goes away, if I floor it, the problem goes away...Steady cruising it is terrible...I tried grounding the TBI in hopes that would help, but it did not...Could it be the Computer??? The car is a an 1989 Camaro 305 TBI.......No noise on FM, or CD....It does not matter if the subs are on, or off....Its driving me crazy....BTW, second Stereo same thing.....I am leaning towards the injectors, or the computer..........Thanks for any help on this subject...Tom

Try unplugging your EGR.
