would a cel due to running a straight pipe cause the ecu to throw it in limp mode?

 

Negative.

 

bummer. was hoping for some extra ponies with the o2 defouler. thank you for the quick response

 

nope. something else is causing it.

 

Whut?

 

wouldn't viagra/cialis help out?

cool

 

ive been running a gutted cat since high school causing the typically cel due to post cat o2 sensor. if by any chance ive been running on some sort of altered fuel map (safe mode/limp) these past 11 yrs, then naturally a defouler would take you back to your original fuel map.

but since that cel code doesnt result in being put into any sort of safe mode fuel setting, then there will be no chance of the defouler bringing back what would have been free ponies for me.

i was just hoping

 

ohhhh! thanks for expounding!

 

the cel is caused by the gutted cats/straight pipe. i guess im not iin any sort of safe/limp mode.

the defouler will get rid of that cel btw. i have nothing else wrong with the car

 

just a point to make.
if you provide details in the Original Post, we wouldnt have so many questions for you to answer.

 

thanks again

Are you talking about P0420 (catalyst below efficiency or threshold)?
