I have a 2000 formula and am having a problem with the Tachometer responding slowly to revs.. All other guages seem to be working properly.. When reving car the tach will respond slowly under light throttle and when under heavy throttle it either doesnt respond at all or is very slow and delayed. Does anyone have similar experience with this problem or have suggestions on what to test or look for??? Thanks for any input..pz
