I put this in here because it has nothing to do with a bonneville or even a gm car, i work in a pretty good sized garage in NH, and we have a shop truck, a 94 toyota pickup, that one of the owners drives, and he is complaining of engine noise being picked up by the am radio while the engine is running. We have tried all that we could think of the eliminate it, with no successs, we have replace all ignition parts with high quality parts, replaced the radio, put in a nosie reducing capacitor, and nothing seems to work.
I was wondering if anyone else has run into a similar problem with any vehicle, and if so what did you do to fix it. Thanks in advance for any help
