#22 of 25 Can MAF Icing cause "Lean" codes? by bigredrasa

In the good/bad old days, carburetor icing could cause driveability problems in cold, damp weather. We have had very cold and damp weather in the last month, and I've had the P171 & P174 codes come on twice. After resetting, they stay off for some time. Could ice build up on the MAF Sensor cause the codes? It could explain why they come on only in very cold and damp weather.

Hi
 New to this forum.I have a 02 windstar. I replaced the isolator bolts gaskets imrc bushings valve stem seals (bank 2 only) valve cover fuel pressure vac line and pcv + vac line. dorman kit 615-177 and still getting the code for bank 2. I was getting bank 1 and 2 before all this. . Odes any body recommend the DPFE, mine is not the metal one mounted near the fuel rail. it is plastic and mounted with short hoses about midway between the egr valve and radiator. also I wonder if I should reflash the pcm (not really happy about Ford charging 100 dollars to fix thier mistake)
 
Thanks in advance

OK i had these problems since i bought the piece of shit a year ago ! both codes came up when inspected thought i lost papers where i wrote them down but found em ! Was told two sensors were bad and EGR valve ! Problems are bad MPG city maybe 11 MPG surges and kicks when stop at light stalls after idling too long etc... I reset the CE light by disconnecting battery van ran far better after that but of course CE light comes back on after about 15 - 20 mins driving !
 
SAW the last answer and i agree has to be in the exhaust or air intake thingy I did spot crack in housing fixed it , and it didnt close too good ! Also fixed that ! I also presume a vacumm leak some where is the problem !
SO after i fix or cannot find a vacumm leak or it's not the air filter housing what do i need to replace That MAF thing or The EGR valve and that too ? I get good used parts at yard where you pull it off maybe cost $15 - $35 tops ! IF they don't work then i go good ol pep boys and get the best priced ones ! I need this van to go another year because I make money with it ! It has 198,000 on it right now only major problem i had was starter went kaput when coming out of Home depot LOL Got it started by rocking van and turning key ! BUT next day wouldnt start 2nd time and had to tow it in total cost lifetime starter $340
 
Has other wacko problems electrical but somehow they just start working right again ! THIS is MY last FORD product ever ! Had EM all Mercury Lincolns etc .. each one lived up to it's name FIXED OR REPAIRED DAILY back words DRIVER RETURNS ON FOOT ! LOL

DIRTY MAF SENSOR fixed my errors. It's easy and cheap, try it first. Buy a can of MAF cleaner, spray it on. Hardest part is loosening the darned gigantic air filter and reconnecting it (this used to be so easy!) Broke 2 fingernails doing this and got my hands dirty. I hate this vehicle!! Simple things are such a pain on it.
