These 3 codes popped up recently on my 2000 cadillac seville sls. Friday it stalled on me but started back up. Saturday it was fine but once I tried to leave ahoerly after turning the car off it wouldn't start. Now It starts when it wants too. Cleared the codes Sunday and drove it fine yesterday morning and afternoon with no problems and no codes. Tried driving it yesterday night and wouldn't start. Today it stated and the service engine light came on and the po741 and p0507 codes come up again. Would these cause it to have problems starting? What do I do to fix it?

P0741 TCC (transmission torque convertor clutch) circuit

P0507 Idle air control system higher than expected

P0101 Mass air flow (MAF) range / performance

Because the engine stalled P0741 would be a result of the engine stall and should be considered invalid. Because a P0507  is set, this would cause a MAF sensor to go higher than expected or out of its calibrated range. so the  MAF  code that is set would not be valid, P0507 would more than likely fit your situation, because it drove fine without any problem, then set a problem , For the fix replace the idle air control valve.
