When i had 2500 miles on my car i've put downpipe on my car with no cat and since then i had my check engine light on all the time right now i have 14k on my car and 2 days ago i participated in autox event, after 2nd run my check engine light was gone. I made almost 200 miles since autox and my check engine light still is off. I'm kind of suprised and happy because of that but i just want to know what happend and how come i had it on for almost 12k miles and now it's gone

 

The bulb finally burned out from on all the time.

 

You drove over 12K miles with the check engine light on?? Are you insane???

 

+1

 

i don't think so because it's still working when i'm starting my car

 

i've been scanning my ecu once a week for codes and it was always only one code for catalytic converter

 

you didn't want to just pay $3 and get 18 mm spark plugs and drill one 1/2 in. to get that annoying light off your dash? your more lazy than i am~ and im lazy! hahaha well good to hear it went off!

 

i tried that before but it didn't work it was like 4 months ago

 

Just get a Perrin 02 simulator, it costs $70-80 and it takes about 30 minutes to install. That's what I did the second day I put the cat delete pipe.

 

I would not have rolled around that long with you CEL on like that.

 

would have saved him a lot of ecu scannings
