i am having a strange timing problem on my jdm gsr engine the engine is stock with bolt on parts such as intake exhaust and honda n-1 lightweight pulley when its idling its about 0 degree (i set the timing light to 0 and the red mark on pulley is above
the timing slot) but if i rev up the engine at about 2500rpm the timing is 16 degree which is right timing but if i dont rev the engine it go back to 0 degree also if i rev to 3000 rpm the timing mark jumps 0 or 16 degree or it dont flash frequent (i am guessing its missing or not firing) i decide to ask you guys before i change any parts
appreciate of your help

 

timing is RPM related the faster the engine turns, the earlier a spark needs to happen so you get a complete burn. now does the engine run good or are you feeling a misfire?

 

at idling i put my distributor all the way toward firewall and only get 0 degree
my car is hard to start when engine is cold and use alot of gas
full tank of oct 91 gas last 370KM (not miles)
