Ok just got a 2003G Sedan and check engine light is on. Took it to Autozone and had multiple misfire and crankshaft sensor on the scanner. Changed ignition coil and both sensors also changed the o.e. y to HR-Y and found the drivers side cat totally messed up the honeycomb stuff came out so had to replace the cat put everything back together car runs good but light came back on and still has a rough idle in park or in drive but as I drive the G it runs strong no missfire, backfire or hesitation. Took it back to Autozone and the scanner has 2codes P011 and P507. Alson took the throttle body off and cleaned it bu noticed a little rattle in it????????????????? So any advice will be NICE!!!!!!!

 

just noticed idle is around 900rpm in park and drive
