What do you mean by plug?
There should be ( from my 2.5 L Duretec knowlege) 2 vacuum line connections. One in the back from the EGR ( exhaust gas reciculation) and one on the front that connects to the front valve cover.
The two electrical connections would be your MAF and IAT ( Internal air temperature sensor). If its a long flat connection, thats your MAF.
If its a smaller square shaped connector then its your IAT.
If its one of these let me know. If I am way off base, tell me what your looking at.

betting the MAF was not plugged back in

Would it even run without the MAF being plug in?Captain KRM P5 said:

sorry, i actually mean IAT. my bad. it would run without the MAF albeit poorly. i am betting the IAT was left in the stock airbox and not installed on the CAI.
theres no place on the intake for the IAT to hook up, the maf is hooked up correctly. we took the IAT off the air box and hooked it back in to the plug, disconnected waited a few reconnected battery after about 5 min of driving light came back on, found its making it run extra lean....took it to sgp racing here in town they said we have to hook it up to the computer and re-adjust the timing and idle....so does anybody know if its safe to drive it this way till it can be fixed or should we put the oem air box back on...untill it can be fixed...thanks for your help...
There is no separate IAT connection for the 6. The MAF and the IAT reside in the same housing. As mentioned, verify that the MAF sensor is properly connected.
The CEL(s) most associated with intakes and the 6 are the following:
P0171 Fuel trim system (RH) too lean ON 2 Fuel and/or
P0174 Fuel trim system (LH) too lean ON 2 Fuel
The greater volume of air that intakes bring into the engine creates differences in the Long Fuel Trim and the Short Fuel Trim. When the ECU detects a large enough difference, these codes are triggered. Yes, the engine is running more lean, but that's the idea given the AJ engine runs pig rich (see AFR in the attachement). Measured AFR's of 6's with Injen intakes show that the lean condition is nowhere near dangerous destructive levels. Past UOA's indicated normal wear even with these CELs, therefore the these CELs are relatively harmless. I suggest either investing in a scanner to regularly check and clear these CELs. Either that or get the Injen fix from CP-E.
P1410 VAD control system circuit malfunction OFF 2 Other
This is a pending code that gets triggered when another CEL is triggered. Basically this code informs us that the green plug connection to the VAD flapper on the airbox is not connected. Just a bit of background, the VAD flapped is a flap that opens on the airbox at higher revs for greater air. As you mentioned, your friend has this plug unconnected. Here's a pic of the VAD connection with the stock airbox:
To resolve the P1410 CEL code so that it never shows up again:
1. Verify that the CELs are what I mentioned and not related to something else. Turn off car and disconnect negative battery terminal.
2. Hopefully you saved the airbox. Remove the brass VAD solenoid from the airbox (the part to the left of that circle).
3. Remove the hoses from the solenoid.
4. Reconnect the green plug to the solenoid.
5. Using zip ties, zip tie the solenoid to somewhere out of the way.
6. Reconnect negative batter terminal. Clear CEL codes that I mentioned.

thanks alot. that green plug is what i've been talkin about just didnt know what it was called did exactly what you said to do with it took it off air box and connected to plug and tucked it out of the way, waited a few and reconnected battery, maf is plugged in very well it was the first thing i checked, i appreciate everyones addvice...
