The check engine light comes on. I know its because of the cat converter. I have taken the positive cable off the battery. The light stays off for a few hours, but then is on again. How do I solve this so that it stays off?

1999 Honda Accord Ex.

 

Replace the cat?

Obviously it's not just going to ignore the catalytic converter problem haha.

So you reset it for a bit, but sees the problem and lights back up.

Just pull the bulb if you're that concerned

 

Light always comes on. When its a code such as cat or a misfire it will take a few hours or even days to come on. If its a code as a disconnected vtec controller it will tell you right away. just replace the cat.

 

if u know it's CAT, then it's mostly likey because u have a bad O2 senor. that needs 2 be replaced.
