Aye fellas good day, i have a 2007 ford ranger xl 4x2, ah few days ago i started getting a hard start problem with it. This problem only occurs when the van is off for a long period of time, when i start after this period (e.g over night) it makes about 4 tumble then starts but with some serious engine vibrations and white smoke from the exuast. This only last for about 30 seconds and the van goes back into normal idle mode with no smoke. It works fine while driving with no loss of horse power. Does anyone knows what the problem with it. Fyi the van is maintained every 5000km full tune up. Any help wud be appreciated thanks fellas.
