Hey guys Im new to the forum. I need some expert advice. I just purchased a 1993 Honda Civic VX with a D15B7 motor. I have many questions. My first problem is How come when I slam on the gas my motor just revs and my car takes a long time to get to a certain speed. It's a 5speed. Is it my clutch, tranny, or timing. Another thing as well when I check the timing to were the top cam has to have the letters UP in the upward direction the car runs fine for a bit after that but goes back to the same problem. What might be wrong? Overall cost to fix? My second question is which ECU do I need for a D15B7 is it a P06 L00,L01 or P05 L00,L01. I love this car but I hope I don't hear that much bad news on how much it will cost to fix.
