Im stuck here guys. I have a jdm b18c1 ( from hmotorsonline ) inside a eg and the car seems to be running to rich. All wiring are correct NO cel. After riding the car for about an hour the gas drop about 1/4 and Oil almost out ( barely on the tip of the dip stick) i had it about 3/4 full no quite to the last dot on the dip stick. And another thing is while the car is warm if i push it really hard from 1-3 after a while KNOCK SENSOR cel would come on. If i park the car and reset the ECU it would go off. But i figure the Fuel running to rich is what's causing my problems. I even have a idling problem when the car is warm. The idle would go down to 700 and up to 1000 and then again and then settles at 1300 this happens each time i make a complete stops while the car is warm up. I bought new spark plugs yesterday after cranking up the car for about 10 min ( off and on ) the plugs are all black. checked wiring and dizzy all seems to be working. igintion timing is compression test is 230 all the way across 1--4.
Im running a JDM ECU p72 could this be a problem and running a CIVIC O2 not integra
