So I am new to the dc5 scene. I just picked up a 2004 rsx type S about a month ago. When driving the car back, I filled it up on gas. My dad did the tank when I ran inside to buy a snack. When we went to start the car it wouldn’t start unless you gave it gas and would stall unless you continued to give it gas. However the issues went away after about 30 seconds of driving. Refilled the tank again recently same issue and same result of it going away after 30 seconds of driving. Furthermore, a check engine light popped up for an O2 sensor and Evap leak. The car does have an aftermarket Apexi catback. Could use some help with these issues cause it’s very strange. Need help with both things!
