Code 1222. Lambda control.
Hey guys. A new code has come up. 1222. It only comes on when idling, as soon as I crack the throttle the light goes off. Also, idle is a little erratic. Not surging, just maybe idling a little too low. Sometimes it almost wants to stall. I figure this is probably an air issue. Any ideas. It has a new MAF, new crank position sensor. Could it be fuel pressure regulator, or another sensor gone bad? Thanks. 1991 325ix.
