his name has vts in it

[riggsy]

So, could be for some one else? His last name might be vts :)

[Burnout_vts]

the problem is, what happens with the second lambda? will the engine light be on?

[hesslevtr]

yes you need a sleeve for it

gmc sell these

[riggsy]

Could buy a sleeve for it, i have one on the way for mine, you just screw it in and tie it up, this should stop the light from coming on :)

If you dont want a sleeve just tie it up out the way, but yes your light will be on!

[Burnout_vts]

will i lose performance if the engine light is on because of lambda

lmao

Have you had a look under the car?

[Predator_R32]

think the nuts come off easier when the engine is hot as it will expand and be easier to undo

either warm the engine up or use a blow torch, id rather run the engine though :y:

no mate, not if your putting a stainless steel manifold on. if your not and your just taking your cat out then yes unless you bung up the hole where the second lambda sensor comes from

[riggsy]

I have a gmc 4-1 manifold and there is no hole in that to put this sensor there fore the light is on untill i get my sleeve.

[Burnout_vts]

lmao

the cat is under the car ;)

[CampDavid]

I'm pretty sure when my ECU light has come on in the passed it's wound the ignition timing back in a bit

[Mark51]

the cat is under the car ;)

just get a replacement pipe then

[S34MER]

all you need is a decat pipe then mate in that case!!
