Hey guys its been a while since I was last here... Hoping that you can shed
a bit of light on this subject.

Ever since I replaced my shattered exhaust manifold on the 4.0 it has been
eating an O2 sensor every year...at least it did till year before last when
like clockwork the idiot light came on with the sensor code...I chose to
just ignore it for a time...I haven't had any unusual problems out of the
engine in this time...no rough running, backfiring etc, like I did when the
sensor got toasted with the cracked header...

Just wondering if the borla header could be the source of the problem?
perhaps it is running a bit hotter/cooler than the sensor would like???


Any ideas let me know by email, as I don't get to the group very often
anymore.

Thanks...

Tommy Humphries

 

I think you may have notice your gas mileage has gone to heck. Some
sealants we are tempted to use like silicone will cook it.

Hey Bill, long time no see.

No silicone products have been used around this critter, and the mpg still
sits between 18-22 fairly consistently. I did disconnect the battery and
the light shut off for a couple of months...it just came back on, which
prompted my post... any other ideas?
