Ok so months ago I had issues with my MAF. I took it to the dealer and they said they replaced the sensor. Now fast forward to last Friday....:mad:

I installed my Qaudzilla with DPF delete and new exhaust at the 70hp setting. Truck ran bitchen all day. Later that evening I pull up to a traffic light and it goes into limp mode. This is usually when it would always happen. So I drive a few miles and it does it again. The next morning I take the MAF sensor out and clean it. I took the filter out and shook some dirt out of it.

Still it goes into limp mode, but only when I come to a complete stop. I really dont want to put the stock exhaust back on and take it to the dealer and we are going out of town Friday.

Does anyone have a clue to whats happening? The code I get is still 0101.

P0101 = Mass/Volume Air Flow Circ Range/Perf

Do you still have your stock intake on?

I had a problem with the MAF and was getting limp and MAF codes and it turns out it was wiring pinched and shorting out. The delaer fixed it so I didn't get to see where it was actually pinched, he said it was in the engine compartment, I would suggest to atleast follow the wiring as much as you can from the MAF sensor back and see what you can see.

check all the connections on the air intake. if its not that, i Know there was a recall on that sensor. if it is an 07.5. buy the sensor and save the time to change the exhaust and taking the programmer out.

I had them change it a a few months ago, Do you think I got another bad sensor or the chevy dealer was full of shiiit? How much are the sensors?

How much are the sensors?

It's showing $192 from GM parts direct.:eek:

Jesus Christ!

Is it possible that my filter is very dirty and its throwing the sensor? There was a lot of sand in it.

yes

could be a dirty filter that could be corrupting your MAF.

Only has 30k on it, but I do drive in the sand sometimes, not often like every other month.

Check the wiring in that region. If not that bring it to the dealer.

Update:
Monday night I pulled the MAF off again. Cleaned it again, but this time cleaned the connections and re-ran the wire. No problems now!:)

cool so it was an electrical connection short huh? good it all worked out.

30 k :eek: of course I`m old and still attending old school. That is why I like using the aFe Pro7 OEM(still using the stock air box)oil type filter.
I have used oil type airfilters for over 14 years now on 12 vehicles and I have never had a problem,the intake after the filter has always been clean from dirt.
I worked(now retired)in a dirty enviroment (for 35 yrs) and the filter needed cleaning about every 4 k.
Even before I made the change using a stock airfilter it was dirty at 4k.
And the cost for the stock airfilter out weighs these aftermarket oil type airfilters.
One suggestion is to stay away from K&N they only have 4 layers v.s. the pro 7 having 5 and they are thicker and different material.
That is why I`ll never believe that a stock air filter could ever hold up to this 30-50K claim, there is NO way in heck.

Unless of course you drive only in a completly dirt-sand free enviroment.

I mean if my aFe was dirty at 4k and they claim a stock filter would still be good for another 26-46K. "BULL PUCKY"
Think about it they both took in pretty much the same amount of air flow and dirt,where would all the dirt go in a stock filter.
There is not a dirt seperator that automatically removes the dirt out a exhaust port.
I think thats what most believe.
Sorry for getting on this rant but I know all the intelligent stock airfilter people will remark on this.

Thats my guess. Funny when I think about it, the problem occurred right after I took it in to have my coolant sensor replaced because it would pop up as low on my dash everytime I hit a driveway or speed bump. So they must have f-d up the maf wires when replacing the sensor. Who knows.

Id like a new intake system but Im poor so Ill have to wait a little while. :(

Suggestion try a aFe proguard 7 OEM(part # in my sig) a drop in the stock intake, for about $70 I think you would be happy enough.
Besides several has had trouble code issues including limp mode with the relocation of the sensor on a complete intake system and the higher increase in air flow.
The increased air flow on a complete intake system is a waist of $$$ if you are NOT planning to push a very large increase in H.P. with the Quadzilla.
You would also have to re-programming everything to accept the larger airflow as well.
Now ! If you plan on making this a race truck then save your $$$ and spend, spend, spend.

Hmm I could afford that!

So its just a replacement filter? The pictures shown on the website look like I would have to remove the stock air box? Or is the real picture not shown.

You can get the replacement filter, and there is also some options for an intake system replacement which would obviously replace you OEM intake.

Call aFe, I have not looked at there website for sometime but when I bought mine in Aug 07 it did not show a drop in for the LMM.
I found out then the 06-early 07 was the same as 07.5 +.

I just checked out aFe`s website they still have not corrected anything.
The 71-10101 is the drop in for the newer 07.5 + LMM`s as well as 06-early 07`s.
They looks simular to the 10-10101 but black in color instead of red and they are the proguard 7.
You would think after 1 1/2yrs the person incharge of the web site would have woke up.
I have 2 filters #71-10101 ,then I can clean at my leasure, also don`t buy from aFe, buy from a dealer you will save a few $$.

Dammit!:mad:
Truck drove perfect all week. Im driving home in the 60mph+ winds from Primm NV this weekend and it does it again at a rest stop! I dont know what the issue is. Its had two sensors and i re-ran the wire. Could it be the filter is dirty?

yeah it might.

yeah it might.


I guess Ill change it out then to the AFE.
