OBD 1 code 1222 problem

[gneus]

I had some troubles with my car lately. When I start it I have to keep manually the revs up otherwise the engine goes into very low rpms and tend to shut off. Also there was the problem with irregular idling, but only when cold and put on Drive. During P, N or Reverse there is no idling issues at all.

I was told to check Air Mass/Volume Sensor, which I did today and the things got even worse. I removed the Air Mass/Volume Sensor, checked it, cleaned it with a rag carefully even it wasn't bad at all and put it back.

I went to try the car. It ran very good for a minute or 2 and after that it died on me while driving. This have never happened before. I waited few minutes and started it. This time I had shaking, smoking(from the exhaust) and very bad idling even on N and P. The engine was in good working temperature.
OBD indicates code 1222, some say is Lambda Control, which has something to do with the O2 sensors.
I don't know what to do any more. If it is o2 sensor how come I didn't get code 1221. What else can be the cause. I am confused and I'm getting desperate.
I need some help narrowing down the possible causes.

1222 Oxygen Sensor Lean/Rich Detect (primary) If the signal from the O2 sensor indicates a very lean or very rich mixture for more than 10 seconds, then the computer generates this code. It could mean a faulty O2 sensor, or a problem with another component.

I got the same code as you, changed the O2 senor and that did the trick.

I guess I'll try to buy O2 sensor today and change it myself. I hope is not hard.
I also ordered used Air mass/volume sensor. Does anybody know if such a problems can be caused by it?

Its one of the easiest things to do, you have a 95 so there is only one. It should be on the right side of the car right by the transmission.

I just changed the O2 sensor and there in no change what so ever, BUT I found that the rubber pipe that is going out of the Air Mass/Volume sensor is cracked many many times in between the rinkles.
Do you think this is it? Is this the problem?

I still get code 1222, even with the new O2 sensor

well, I taped really tight the whole area where the pipe was cracked and now FINALLY everything works OK.
I am waiting on my new pipe to arive. Problem solved!!!
