B20v check engine light problem

- Fri Oct 18, 2013 3:36 pm #337799 Hi there, I've a few question looking for answers from all the experts on civic. Now to my understanding, when we turn the key to the ON position, the engine check light and oil light will come on for awhile then go off. However, in my B20v, it stays on until i start the engine then it will go off. Now, is this normal, or it signifies some problems? Another problem is regarding the RPM. My stays at 0 RPM at idles never mind it's warmed up or cold start. The needle also go back to rest at 0 RPM when coming to a stop after driving. One last thing is that my speedo went hay-wire recently. It will not move as the car move. It just stays at 0 Km/h. Some times it will starts to operate after driving for awhile but sometimes it don't. Please kindly enlighten me why all these abnormalities? Tks alot....
