Ok so I have a very strange problem with my car that has some symptoms that I have never seen on any other car ever. I would like to get it fixed, but I have no idea what it could be. All I know is that it is running rich. Throws a code for bank 1 richness once every blue moon, but always goes away after turning the car off. So far I've checked the fuel pump, fuel filter, fuel lines, and intake stuff on the off chance that there was a block restricting air flow. Pump is good, fuel filter was replaced, all lines look just fine, and all intake stuff is fine (even cleaned the IACV for good measure. Aside from maybe injectors, or something fuel rail related I don't even know where to look to next. Any help would be appreciated, would rather sort out all the simple stuff myself rather then let the shops rob me.
Symptoms:
-Rough idle when warm. Only happens when warm and doesn't always happen. I'd say its about 50-50 shot when I come to a stop my idle will drop. Drops down to about 350-450rpm when this happens, and makes the car shake so much that I can feel it in my seat.
-Sometimes when this happens it will cause the engine to start knocking. I'm going to be an optimist and say that its just the motor mounts making noise due to more engine movement at such low rpms, but I've also heard that over time letting the car run rich can make you develop a knock.
-Car will die randomly sometimes. I don't mean sputter, I don't mean lose power, I mean die instantaneously... No matter what RPM or speed I'm going. It is an instant engine cut causing me to lose brakes and power steering (as if the key was not even turned) After this happening usually I can put it in park and just start the car and continue on as if nothing happened, however sometimes it takes a while for the car to feel like starting again.
Again, my car does not have a check engine light. It only comes on with the code for bank one running too rich every once in a while. Maybe 3 times since I've gotten it rebuilt last spring, and it never stays on. Always goes away after a couple days, or after turning the car off.
