hey guys.
So i've got an ek1 running a stock d16y4 with very minimal mods (only intake and headers) and its been giving me very bad fuel consumption ever since i bought it. Thought it was normal to get 400kms~ each tank but recently i've been reading about d16s getting 500km+. I was wondering where to start to fix this problem as it is my daily driver. I dont know if its related to the problem but my fuel gauge goes down very quickly and can get down to half-tank with about 150kms from filling up!
I read that replacing the fuel filter, air filter and thermostat was the way to go. Maybe replace the spark plugs and o2 sensor too? I'm not too sure of where to start?
My second problem is that on early morning, cold starts the engine would make a high pitch noise. Sometimes it would be for a second and other times it can go for longer. Mind you this is almost every cold start and its starting to get annoying so i want too fix it asap.
Please let me know what I should do to fix these problems up.
Henry.
