i found a hold in my DC header, could this throw a code 43?

 

i don' tthink so code 43 is a fuel code it will give ya an exhaust leak which still needs to be fixed though

 

A hole in the exhaust can show up lean on the o2 if its before the sensor.Fix the leak,clear the code and give it a try.

As far as I'm concerned, THERE IS NO SUCH THING AS A FUEL CODE. There is a code that indicates a problem with the fuel supply system, like one of the sensors the computer depends on to provide the right amount of fuel. Like an oxygen sensor...

Fix the hole in the header, your code will be taken care of.

 

Yeah, the O2 sensor really measures the DIFFERENCE between inside & outside. So if there's exhaust blowing over the outside of the sensor, that throws off the readings, & the ECU doesn't 'understand' why all it's different measurements don't add up.

 

ok patched what i could see,with thermosteel, i guess ill take the header off this weekend and go all around the weld, the CEL is random some times it will come on some times not, but usally it will but at random time during driveing, if this dont fix the code what would the next cause be?

 

As if my car was reading this and wanted to reinforce what I said....

My car started surging and hesitating today coming back from work. It started losing power, and that Hyundai in the mirror was coming up fast. I was thinking "oh ****, the rings are in the oil pan" as I watch the air/fuel ratio go nuts. I started to hear a hissing noise when I got closer to home. I park it and pop the hood and see a HUGE leak in the exhaust, where the manifold meets the downpipe.

Moral: Giant leaks in the exhaust before the O2 sensor cause it to read incorrectly and throw off air/fuel mixtures. Also my car is a money pit.

So there's a Honda continuum too? I thought that was just Saabs. There's always gotta be some constant number of Saab problems in the world. When you fix something, there's another Saab somewhere that has to break.

LOL, I've heard that about french cars too. I just stay out of european cars all together, they have that "if it's not leaking, it's empty" thing going on, among other problems.

 

its not a giant leak, its cracked around the weld, but its is before the O2

 

i fixed the hold, but still the CEL comes back, any ideas?
