Shortly after I fixed the P0303 code problem, I got a P1124 code. If I
disconnect the battery, the code goes away for approx. one day and comes
back. I see that there are a lot of components involved with this code. Is
there a common fix? Any help would be appreciated.
P1124 refers to a lean condition at idle. Since you repaired your intake
leak with some rtv without removing the intake manifold-- that was my
impression upon reviewing the P0303 thread-- you probably still have a
small leak there that's not enough to generate a misfire.
Since we've already established an intake manifold problem, I'd recommend
starting with replacing the manifold gasket and then clearing the lamp to
see if it comes back.
