I have a 1986 bmw 528e and ever since I got it I have had to replace fuel filter, fuel pump relay and a fuel hose. After I replaced the fuel hose my car started having an erratic idle, it goes real high then drops real low, up and down continuously. What is the problem exactly? My guess is that it is the idle control valve. Am I correct?
