Hi, I'm havin' a lil problem w/ my civic. when its hot outside and I go to start it up, the car will fire up and rev up a lil (like it normally does) and when the revs drop back down to idle it skips idle and stalls out, then it won't start up for like about 5 min. Now I was wondering if it could be the fuel pump, fuel pump relay, or something else? The car threw ecu codes while driving earlier: 1, 41 and 43. (o2 sensor and fuel-system). I was wondering if it could be the cause of my problems starting the car, if I start it up an rev it up a lil b4 it stalls the car's str8. Any feedback appreciated, thnx.

PS. Also I hear lil ticking noises from my engine and someone mentioned that it could be the injectors clogged. any info on that?
