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.

Thanks,

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.

hyundaitech, you are the man, you are right on time again. Found another
small intake leak, repaired it, no codes. Thank you for your expert
diagnosis and help.
