AIV EGR solenoid

Which is which?

May have inadvertently hooked the wrong hose to the EGR valve after plenum pull and bypass.

Got a mad lumpy idle like its all cam'd up, but its not

Revs fine. Just lumpy idle.

Going to do a complete overhaul of hoses in the morn. Hoping someone can point out which is which to save taking the guard off and chasing AIV lines.

Which one is the stock boost gauge sender plumbed into also?

Thanks in advance.

Throw both in the bin

 

There are vacuum hose diagrams in the Nissan Factory Service Manual.
You don't need to look under the guards, the hoses are visible in the engine compartment.

 

Why?

Why would you do that if they are working correctly?

 

That's not very helpful, I spent 7 hours reading up on all the vac hoses under there last night before I posted. Wanted some confirmation.

Fsm diagrams are shit to read FYI

But I thinki remember reading somewhere the j spec ones are in dif locations.

Ill sort it out

 

He means the AIVs. Might as well remove them as they never helped from the start.

 

Sorted.
Someone has previously tried to bypass the EGR ended up the AIV was operating the EGR and vice versa.

Running smooth as, actually never run better.

AIV delete is on the cards. Someone has also disabled the carbon canister atom purge off the throttle body, no idea if they blocked the pipe off the canister or not will check out later.

 

Fun times sorting others mess. Glad you are making progress

 

It's running like an absolute dream Jonno.

I may have to not drive it so it stays that way
