so i followed the instruction to decode my ecu problem, first time testin showed knock sensor problem and somethin else (i forgot), i turned off my engine and did a 2nd time, it gave me 0505 no problem, 3rd time it was also 0505, so did the 4th time...

i reset my ecu, CEL is off... it's been 2 weeks or so and my car is runnin fine, so here is my problem: should i do a ECU check again? should i check my knock sensor and tat "somethin else"? or i should jus ignore it?

please help me.. cuz it's botherin me when i'm driving....
