Good place to check. If everything looks right and your still lean, a vacuum leak is a possibility. And as lean as you are, a big vacuum leak would do that.

So I got the carb cleaner and started spraying everything. Nothing was changing. Then I sprayed the EGR pipe at the base of the LIM. Every time I spray it, RPMs rise about 150rpm. So I sat there scratching my head.

I hooked up my laptop and loaded hptuners, and started scanning, and sprayed it again. Every time I sprayed it, STFT'* would level out and o2 readings would shoot up.

I think I found the source of my vacuum leak. Carb cleaner must have cleaned it out some because now you can actually hear the vacuum leak pretty well.

So where do I get a new one? Nobody seems to carry the damned thing anywhere.

How much do you want for one.

How soon can you get one out for me?

Where did you get them?

Well, you do have HPT, I could charge you $20 shipped, or you could disable the EGR in the tune, and then block off the hole.

How much of a difference does EGR make in regard to fuel economy?

I don't think you will notice anything. However. remember how dirty your throttle body, supercharger, and LIM was? Without the EGR that will all stay clean. To disable the EGR you will need to set all the DTC codes for the EGR to #3, no error reported. click the SES box to remove the check mark. Do this for codes 401, 402, 403, 404, 405, 1406, 1409, I think that'* all of them. Then go to engine, pick the general tab, and set the temp to 284. That way the EGR will never turn on. Your car will pass emissions. Block off the hole in the LIM and your set. You can leave the EGR valve on the engine, it will keep the exhaust hole blocked off. Also, if emissions does a visual check it will still pass.

I think I'll do that. All that carbon buildup does **** me off a lot.

What would you use to plug up the hole? Just get a bolt?

I made a aluminum plate and bolted it in place. a bit of copper RTV and you should be set. If you really want to make sure it'* sealed you can fill it with JB weld.

Sounds like a plan. I'll do that.
