Don't understand why, since it goes away  with the lights off.  Strange thing
 just as the engine speed passes through 3500 RPM and then again when the
revs drop back down through 3500 you hear that 'TING" sound. Anyhow I did
change the fuel filter not very long ago,but at this point I'm willing to try
anything........thanks.......I'll let you know the result when I do it.
