Thread: 97-03 NA L36 UIM Failure

I also read what Rico said about it being a pain to pull or change out the stock tube. I'd almost think that you'd have to cross drill the tube and use a puller of some sort so you didn't have to kill yourself getting it out. The only other option I thought of was putting the narrow stovepipe in then wrapping it with a thin layer of that white heat fiber wrap they use in high heat applications. It will take direct heat from a torch and not even discolor.
Regardless....I have hex type (drive) aluminum threaded plugs in the shop and I think they'd fit flush, but unless I missed something, would there be any issues with the throttle body and/or it throwing codes ?

To remove the old tap from side to side with a dead-blow hammer and it will loosen. Grab it with a good pair of channel locks and twist. I also put a piece of wood on the LIM to pry upwards. I was worried about ruining the hole in the LIM.

I don't think you'll have to worry about it if you use the new thin style. This creates some distance between the pipe and the UIM.

Could you please elaborate on your last question about the TB and codes?
