urgent help with 626 IM install

[619MSP]

i am doing the 626 intake mani install and i an having a problem. i bought the 626 install kit from pg and the egr pipe is not working at all! i just read that you can just plug them, but how would i go bout doing that? heeeeeeeelp me

 

[theEZV]

get a cap for the exhaust mani. small filter for the intake mani

 

[JCell]

how about u install the stocker back until u get the right piece?

u cant just put a filter on the IM, it will leak under boost and u will cut up the egr

 

[619MSP]

but i can plug up the exhaust mani right? can i plug the im? so it wont leak

 

[JCell]

yes, u can do that. its how i have mine setup. but u will get a cel

 

[619MSP]

u have them both plugged? and the cel, will it be anything that henders the performance of the car? any side effects?

 

[JCell]

afr will be affected. but other than that no

 

[619MSP]

how will my afr be affected?

 

[JCell]

because its setup up to run with the egr gasses running through it.

 

[619MSP]

so will i need to make any changes to my tune to take into account for that? and how far will my afrs be off?

 

[JCell]

depends how aggressive your tune is. mine knocked it a full point leaner

I finally got the EGR pipe to work... 2 HOURS LATER!!! Thanks for the help, because another 30 minutes later and i woulda just plugged it

 

[yudkib]

well now i need to know about this...

i got a new EM which doesnt have a port for EGR. and now im getting p0171 - or as i now call it, "the problem code". is this because its leaking under boost?

 

[dacquesta1]

is your im plugged? no egr flow is going to cause a cel

 

[yudkib]

no, my IM has the EGR pipe still attached with a breather filter.

 

[dacquesta1]

i would think that would cause a boost leak. i may be wrong though..im not turbo

 

[KrayzieFox]

No, that is not your problem. When I had my boosted P5, I had my EGR setup the same way after installing the 626 manifold. Left the pipe bolted into the IM, cut it a couple inches from there, and put a breather filter on it. Ran it that way for at least a year without any problems or CELs.

And full boost too. No leaks.

 

[dacquesta1]

well there you have it lol. still have much to learn about these turbo setups.

 

[KrayzieFox]

EGR operates by vacuum so that gas travels only one way.. from the exhaust into the intake, so under boost/positive pressure the passage is closed or otherwise you would be leaking boost with or without the EGR pipe hooked up.
