[Hi Ho]

Well I bought an oxygen sensor socket and replaced the dang thing. The engine runs noticably smoother. I thought it was running smooth already. I drove to town yesterday and the check engine light didn't come on. Today I went further, to Olympia and the check engine light came on twice! Now what?! The magic red light under the carpet (the computer) tells me... well I'm not sure. According to the manual if there are zero blinks the computer isn't working. If there is one blink it is either the oxygen sensor, pressure regulator, or spark plug misfire. Now, the light blinks as follows; one short blink, pause, one short blink. I'm not sure what that means. Basically the manual is telling me that if there are no blinks there is a problem and if there are blinks there is a problem. So what means everything's working fine? I'm confused. I don't know what's not working now. There is definetly no mis-fire. I'm not sure what effect a bad fuel pressure regulator would have. Any ideas?
