Hello everybody
I am new to this group - this car never bothered me before, it just worked (bought it new, probably the last one made in Japan, manual SE).
Now, something happened to it, don't know when and how, I wasn't the on who was driving it for the last few months. It feels like the car lost power, engine seems to miss from time to time (the car sort of shakes back and forth - not unlike what they do when you try driving them in a too high gear at a too low speed). It does
*not* happen when the engine is cold. I don't think I can hear any unusual sounds. Checked the codes at Autozone; they said they see P0325 showing up twice. Few days later the engine light turned on. Checked the code again, now it's 0303 (once). They reset the computer, the light didn't turn on since then. What else? Air filter is new. I guess fuel filter and pump has nothing to do with the problem since there is no problem when the engine is cold.Not that I don't know about cars - I had an old Jeep YJ once, it should tell you something ;) But I can't quite figure what this problem could be related to. If a spark plug or a coil were bad I'd be getting codes all the time, wouldn't I? If knock sensor was bad, I'd be getting 0325s all the time? And, how a bad knock sensor could cause these engine misses anyway? It seems to me there may be some weird coincidence and the culprit is somewhere else... Is there any vacuum line that kicks in when the engine gets warm, by the chance?
BTW, all internet sites say knock sensor is on the driver's side. In my car its on the other side, and it's held in place by not by a nut, but by some aluminum thingie with a screw in it. The harness is also different from the one they sell for 99 Maximas, what the hell... But anyway...
Please - what do you think is happening to this car?
