I have a 2002 5 speed manual mustang and i just installed a mac o/r h-pipe and axle back. i had to extend the two o2 senors closest to the engine. Could a bad connection in the extensions be causing the car to stall(only stalls when when at idle) or is it something else??

Thanks for the help!

Do you have long tubes, I don't see why you would have to extend the 02 sensors with a full length mid pipe considering there a generous amount of extra wire with them.

Is it throwing a code?
I'm guessing it isn't that there is a bad extension as much as it is just that the sensors are further back in the flow so they are getting different readings than if they were in their stock locations. Any time you do work like this you really need to think about getting a tune to compensate for things like that.

Just had the codes read today all came back for o2 banks running lean(expected this) but i did get a code p0443 looked it up something to do with the gas tank purge valve could a bad valve be causing me the stalling issue??
