03 STR, Mina Intake, Both banks lean (P1410)

Hey all,
Long time lurker first time poster![Icon Special](https://www.jaguarforums.com/forum/images/smilies/icon_special.gif)
Just had the dreaded coolant house under the blower replaced after the car sat for about 6 months
and of course on the way home from my mechanic the CEL came on...
I pulled P1410, both banks running lean. I'm assuming this is from my Mina intake. A couple threads on here just instruct to put the stock box back on but I no longer have mine + I would really like to be able to use this sweet, sweet cone![Big Grin](https://www.jaguarforums.com/forum/images/smilies/biggrin.gif)
Any suggestions on how to remedy this?

Seems to be the exact same situation.

I'm sorry, I'm confusing myself. My mechanic pulled three codes, the first being that p1410, then the next two (although I don't remember the numbers) where that both banks were running lean. I'm assuming that all three are related to the mina intake.
I no longer have the flap or original box :/ and I would really like to be able to use this intake.

Been digging around on the forums for a bit, think I might have a viable cause.

This thread talks about this code and the engine running lean. Brutal says that the p1410 flap code is nothing to worry about, but the engine running lean is possibly coming from many things including a weak battery, and it just so happens from sitting for about 6 months my battery was dead for a a long time and is probably not 100% at this point. Brutal also talks about it possibly being a bad secondary fuel pump, but I ruled that out because the fuses he says to check are still fine. It just so happens that another symptom of a weak battery is misfires and I was getting some of those codes about a week ago as well.
I'm gonna go buy a new battery and report back!

New battery seems to have fixed it! No longer in restricted performance! I think I figured out why. It seems that the weak battery was causing misfires in a few cylinders causing the engine to run lean. Gonna run by my mechanic this week to see if all the codes have been remedied.
Hope this helps someone!

P0174: Bank 2 combustion too lean
Possible Causes (for both):
- Engine misfire
- Air intake leak between MAF Sensor and cylinder head
- Fuel filter / system restriction
- Fuel injector restriction
- IP Sensor fault (low fuel pressure)
- Low fuel pump output
- HO2 Sensor(s) (1/1, 1/2) harness wiring condition fault
- EFT Sensor fault (low fuel temperature)
- MAF Sensor fault (low intake air flow)
- Exhaust leak (before catalyst)
- ECM receiving incorrect signal from one or more of the following components: ECT Sensor, MAF Sensor, IAT Sensor, IP Sensor, EFT Sensor, TP Sensor
Game Plan
Since a couple of you think it is showing these codes because it is pulling hot air, here is my plan.
- I still have the intake tube (number 5 in picture) installed. My plan is to make a larger more insulated heat shield that will have a port cut out for the intake tube(#5) to fit through and provide cold air to the mina intake. I'll use weather shielding to create as tight of a seal as possible between the heat shield and bonnet. And some heat reflective tape. This should only cost at most $50 and is worth a shot I think.
- If that doesn't work, clean the MAF
- If that doesn't work, replace the MAF
- If that doesn't work, purchase a stock air cleaner assy and install

Any input would be appreciated. Since the I just put quite a few $$$ replacing breaks, every o2 and knock sensor,a bad motor mount, and the dreaded coolant hose under the S/C, I am trying to be as easy on the wallet as possible.
Thanks,
Dan

Begnning to sound like a pretty expensive Mina intake! As I recall, a new airbox costs between $300 and $400 - I got a filthy, dust-laden used one from a California scrapyard, complete with WOT flap, for $152 plus postage.
May be a dumb question, but... is the insulation lining on the underside of the STR hood in good condition? I mean, that's the other half of the airtight seal.

We'll see if that fixes the problem.

Lots of stuff has to come off for the hose replacement. Including stuff that can cause a vacuum leak if not properly replaced.
There is also the fact that the stuff includes all kinds of electrical connections.
