Hey fellas. I'm gearing up to pull the intake manifold on my '99 TL to clean the EGR ports.

The instructions in the Acura bulletin say to replace the throttle body gasket. I've read the many DIY instructions on this board and no one has mentioned replacing it.

I know it's a cheap part-- I'm just trying to avoid a trip to my stealer if I can.

Thanks

 

Pick one up while you are out buying some Throttle Body Cleaner $3-5- not same as carb clean
Spray liberally as directed

Better safe than a manifold vac leak

 

There is no need for removing the TB when just cleaning. . Keep it attached

 

anyone know the DIY thread on doing this?? id like to check it out

 

actualy im going to write one up in a day or 2 when my spacers come, i just cleaned my egr and manifold 2 days ago, but im going to take pics when i install the spacers. fyi i didnt remove the throttle body when i cleaned it. its not nearly as hard as i thought

 

do a search for EGR Cleaning. The DIYs are out there. It also depends on what year you have. The 99 is different from the 2000-2003

 

k well if anyone can post a DIY for a 99 or even the difference between would be huge

 

the one ill be doing is for a 99, give me a day or 2

 

Ok ill bite. ill do all the work for you. Like i said, use the search button. the DIYs are already out there. (also found in the DIY mod section)

Kris,
Question. What if I have already replaced the EGR valve, cleaned the intake and I'm still getting the Insufficient EGR flow code? What else could be done?

EH

 

when you cleaned it did you take the upper intake manifold off to clean it out? did you clean all the little tracks in the upper cover, and did you clean out the lower intake manifold to egr hole?

 

Yes, yes and yes.

Granted I did all of that six months ago, and I replaced the EGR three weeks ago. But since I gave all you mentioned a great cleaning, I didn't bother when replacing the EGR.

You're probably going to tell me that I need to clean all of that again, right?

 

how would u go about cleaning the lower IM egr hole. it was dirty also but i idnt want to spray anything into it or the lower IM

 

something is still dirty causing it. Thats the only thing it can be

With the upper IM look into the port to see if its dirty/clogged. If it is you can use a small pope cleaner brush and some cleaner. Take the EGR off before doing so.

 

Thought so. I'll get to that in the next couple of weeks. Thanks, Kris.

 

*EDIT* how do i got about cleaning this egr hole, theres a buncha shit stuck in there
i dont want the crap falling into the hole

 

I never replaced mine, but I know the Oreilly by my house had them for like 5 bucks. I would buy one just in case it is in bad shape by the time you take it off. I just didn't feel like driving there. The autozone near me didn't have one but could order it. You don't need to go to the dealer.

 

Scrub brush, compressed air/shopvac. thats why i recommended taking off the egr as well.

 

Kris,
Aside from the insufficient EGR flow, I'm also getting the following code: P1457 Manufacturer Contrl. Auxiliary emission controls

Any idea as to what can cause this and how to fix it?

 

BUMP.


Comments please.

I was kinda curious, so I googled it. This may be what your looking for.

Thanks, bro. I really do appreciate you finding that.

 

Beat me to it. There are many things to try. I would use the link to try what was mentioned. But i would do it only after you have cleaned teh egr ports so that its not causing a code

 

Thanks, Kris. It has been throwing both the insufficient EGR flow and evap canister code for a long time now...and I can't see to get rid of it.

Some of the procedures mentioned in that link are a little unfamiliar to me...Any pointers?
