Hi was wondering if any one can help me, I have a 1992 KH S 1.8L fuel injected Ford Laser. It's idling rough and sometimes stalls. I have replaced plugs, leads, fuel filter, air filter, oil, oil filter, distributor cap, rotor button & timing chain. But it still idles rough and stalls. When it's warmed up the revs sit on about 500 and fluctuates between 250 and 500. What else could be the problem? It's driving me crazy. :sad: Any help would be greatly appreciated. Thanks in advance.
