Symptoms: only 7 inches of vac. not enough for fuel pressure regulator to control overich condition car runs@exact timing marks 10 BTC, have also tried advancing cam to #2 & #3 positions on cam sprocket no difference,have even advanced cam sprocket 1 full tooth (it still runs). :stupid: any input is appreciated Thanks
