After some trouble shooting, research and downloading the DTC code (P0101/0171/0174) I have determined that my idling problem stems from a polluted MAF sensor. I also run a K&N filter. After watching a video on cleaning the technician reccommended useing only MAF cleaner. It (MAF cleaner) appeared to ressemble electrical contact cleaner. Do I assume correctly/incorrectly? Please advise. I have contact cleaner but not MAF cleaner and the truck is my only means of transportation and I'd rather not drive. Thanks in advance.

Get sensor safe MAF cleaner from the parts store of your choosing

I'll take your word as gospel. I'll get a ride. Thank you.

BTW Chris. Given my above mentioned symptoms do you concur or not with my conclusion?

Having a K&N the Maf could have the filter oil on it. I will admit I had problems from over oiling my K&N before. It might not be your problem, but it is normal maintenance to clean the MAF and a great place to start when having MAF codes. Both banks being lean with a MAF performance issue could be from a dirty MAF, If not a malfunctioning MAF

DO NOT AND I REPETE DO NOT use contact cleaner to clean the MAF, use only sensor safe maf cleaner. Using contact cleaner WILL destroy your other sensors in your motor some instant and some over time.

Thanks for the re-affimation. Arranged a ride tomorrow to AutoZone.

Never had a problem using electrical contact cleaner that doesn't leave behind a residue. But if they make a MAF cleaner, sure go for it.

Sounds like the root cause of the problem is the oiled filter.

 

If the purpose of replacing the factory filter with an aftermarket filter is for "better performance", and yet the use and deployment of the aftermarket filter leads to the engine throwing codes and having to hitch a ride to the auto parts store, then is the performance really "better" than stock?

 

I run the high capacity stock air filter, and never once had a single engine code set. A "better performing" air filter is one that allows the truck to run trouble free, without worry about not oiling the filter enough and dusting the engine, or oiling the filter too much and fouling the MAF, or oiling the filter every other month so as to keep it oiled, but not over oil it. That's a lot of worry and work. Then on top of that, deciding what to clean the MAF with, and worry about the long term effect of the substance on other sensors. Yikes.

 

Interestingly enough, the GM Performance Parts aftermarket filter makes a point of advertising that it is not oiled. That speaks volumes in and of itself.

 

The GM factory High Capacity stock air filter has a huge amount of surface area. It will flow all the air a naturally aspirated engine can suck in. At the end of the day, it might be the best performing, when considering the inconveniences of the oiled aftermarket alternatives.

if the contact cleaner is dryed off of the MAF sensor ,,,how will it destry other sensors ?

A maf is just a wheatstone bridge of resistors.... not rocket science. As long as you don't break, coat or melt the resistor you won't hurt it. Yeesh

If your oiling your cold air intake filter every month, you are doing something VERY wrong. When properly installed and maintained as per the manufacturer's instructions 99 times out of 100 your not going to run into any problems. But there is always that 1 person out of 100 that will...

    • Thanks @newdude, guess I'll keep looking.  Test driving so many trucks that have obvious things broken, I'm thinking "if they couldn't even be bothered to fix the power seat," what else is broken".   Just drove a 2021 where the power seat motor was grinding/binding and wouldn't do anything but make a terrible sound.   An owner that puts dents on the bumper, doesn't fix a seat motor, and had spotty service intervals (along with missing major services) doesn't give me the best of confidence.   Amazed at the number of people that will finance a $60k+ truck, run it into the ground, then trade with a loan balance (every single one had "loan/lien reported" on the CARFAX at the last year of registration).
    • Not true! I have been runing them since 2006 F250! suspension component that works as a sway bar, a traction bar, and a helper spring points directly to the RoadActive Suspension (RAS) kit. Works as a sway bar, a traction bar, and a helper spring.
    • Here's a starter kit:    CC Jensen, a Danish oil testing Concern gives us the following guidelines:   ISO 14/12/10 Very Clean Oil ISO 16/14/11 Clean Oil ISO 17/15/12 Lightly Contaminated ISO 19/17/14 New Oil ISO 22/20/17 Very Contaminated and not suitable for any service.   In addition CC Jensen gives a table showing how engine life is increased by cleaning up the oil. For example cleaning the oil from 19/17/14 to 13/11/8 will extend motor life by a factor of 6X.   But even cleaning it two “Life Extension Classes” will double motor life. So perhaps giving those classes would be useful:   21/19/16 20/18/15 19/17/14 18/16/13 17/15/12 16/14/11 15/13/10 14/12/9 13/11/8   *************************************   https://testoil.com/program-management/setting-iso-cleanliness-targets/   Third paragraph from the bottom will give a starting point.    Your next question should be, okay 10um at what Beta ratio and the answer is in the graph Beta 75.   Then the next question is what is your chosen filters profile? (Purolator PL series below) The red dot is Beta 75. This was the information I obtained from MANN a few years ago. So the best filters, Purolator One, AMSOIL EA, FRAM Ultra, Royal Purple, Bosch Premium should get a doubling engine life over filters like Purolator L, any service filter from any quick lube, WIX, NAPA, STP, Mobil 1, Purolator BOSS.    And as noted by CC Jensen a 2-5 micron @ Beta 200 bypass system has the capability of a six fold improvement. AMSOIL has such a system as does Donaldson.       Now having said all that testing is the touchstone. Test the oil NEW and test it with your chosen filter. Then test over milage. Do the work, get the result. But understand this in NOT absolute BECAUSE this is one factor in isolation.   Example:    A valve spring supplier can state that with cam X and a valve train of Y grams the valves will not float to 7K rpm. is that true if the builder choose a system 20 grams over limit? Common sense must be used and limits understood. 
    • This doesn't look like a GM truck. Not needed on a HD truck
    • It varies a ton around me. Some places are still at $5.00 or higher and others are way down into the $4's.   Offroad diesel was $4.02 at the one station I passed today.
