Headers

[BYprodriver]

If you have never replaced the front engine mount replace with the 987 mount. If you have replaced the mount repost & we will try again. Please tell us how your O2 connections went, any CEL?, P codes, header brand? Sorry to ask for more info than I gave but you write so well & didn't want to miss this chance.

On the sensors I basically cheated, just used the O2 sensor defoulers. At first I used some short straight ones---wasn't enough, still got the CEL. The codes were:

P0133, P1275: Aging of Oxygen Sensor Ahead of Catalytic Converter (Cylinders 1 - 3) - Below lower limit

P0153, P1276: Aging of Oxygen Sensor Ahead of Catalytic Converter (Cylinders 4 - 6) - Below Lower Limit

Not sure why the codes are regarding the O2 sensors ahead of the cats. I would think that by eliminating the first set of cats, codes would be for the sensors after the cats. (I'm also unsure why there would be, for each cylinder bank, TWO codes that indicate the same condition, ie P0133=P1275, and P0153=P1276.) Anyway, I ordered this:

...and the extra length + the angle seem to have done the trick. It's been at least 100 miles and no CEL so far.

BTW, I did the front motor mount (a Pedro-refurbished one) about 3k miles ago.

The headers were some Turbowerx knockoffs from ebay. As I said earlier, they do seem to be well made, in spite of their affordability.

Hey @Frodo,

Sorry to reincarnate an old thread….but how is your HEADER SOLUTION working? Are you still throwing CEL codes? Did you flash the ECU or solve it mechanically? Where id you get the "L-shaped" sensor extenders and do you have a part#?

Inquiring minds want to know…especially since my headers are due in tomorrow!

Thanks!
