check enging light came on. ran a code. egr valve clogged. problem is....honda sucks nuts and won't cover the TSB because it ends at 80k miles and i have 83k.

anyone DIY? Where is it? right near TB just below it? I haven't even looked yet. How did you clean it out etc.

The best way would be to remove the intake manifold and clean out the EGR port. If it was mine I would drill it out to about 1/2".

 

OK, now why? is there a performance gain? do you think it is poorly designed? is this on the V6 only?

 

By drilling it out, you mean. Yes, I think they are poorly designed, and I would guess Honda thinks so too since they have us drill them out. (Per service bullitin #99-085.)

 

sounds fine to me. any way of tricking the ecu not to throw the code? or will the ecu not care how big its ported...just that its not clogged

 

Drilling it out keeps it from clogging up as fast. The EGR valve controls the amount of flow.

 

Since i'm not sure if your joking on the size. were you serious about the half inch porting? Until i visually look at it.....i'm not familiar with its current size

btw. thanks for the help

 

Yea, some of us drilled them out to 1/2 inch before the bullitin came out. You have to be sure to follow the same angle as the original hole though. I don't know how much extra meat there is. It's original size is about 8mm.

 

Jeff -

I know with 5th gen accords you can use a thin sheet of metal over the EGR and it will trick the ECU into thinking the ECU is functioning fine. Several guys in this forum have done it. I havent. Hopefully tomorrow when more people get back to work you can get a more specific answer. The sheet of metal over the EGR is an old muscle car trick.

 

That wont work on a 6th gen. The ECU checks for EGR flow by watching the MAP sensor voltage. It would be kind of hard to fake that.

 

very much appreciated guys

 

Well there you go. lol

 

thanks. you helped alot. I'll get cracking on that manifold
