Today several times, I keep getting the P0171 code, I reset the scangauge since its not running any different....and it comes on within about 15 min of driving.....FPR Jay replaced for me awhile back....throttle body was cleaned last week when they did the timing belt and stuff.....guess I will clean the MAF and see what happens....AND I was on my way to get it inspected when it did this so I will try tomorrow
Interesting addendum.....I just swapped out MAF sensors off my other VX and noticed my rubber edging around my green filter is totally melted away, filter is 1/2 laying in the air box.....and I just had it out and cleaned and oiled it a couple weeks ago.....so it looks like I am on the hunt for a local green filter...
Just wanted to add my experince with 171 lean bank codes. I tried alll the above but was surprised to learn that it was leaky common chamber gaskets. Seems there's a service bulletin on these things being over-torqued from the factory. They should be 13lbs, or hand tight, anything more and the bottom one cracks and leaks air. Once I changed those gaskets, it was a new truck. It has never run smoother. To check your gaskets, start it up, and spray around the edge with carb cleaner. If it revs up slightly you've got a leaky gasket. Change it, you'll be glad you did.
I know it gets hot in Texas, but dang....:freek:Quote:

Lisa, don't they have a life time warranty like the K&N's? Might want to contact Green for a free replacement!
Thanks Billy, emailed them yesterday! I am using cheap paper filter in the time being!
No problem...in these times you can never save enough!:happyface
My 171/174 woes have been intermittent for the past year. I ended up just learning to deal with staring at the CEL.
FWIW, I have no vac leaks and MAF cleansing never helps. Considered the o2 sensors but just never got around to it. In a sense, it's really not a big deal to me since I only drive it on Sundays, heh.
Well, it's been on for the passed few months straight and things are normal as ever. I gassed up yesterday and I recall when I was putting the gas cap back on, I had some difficulty just cause I simply wasn't lining the threads up well. Well, once on, I gave it the super duper annoyingly amount of turns and clicks. Just for good measure cause I felt like an idiot trying to get it back on. :p
Once back inside and ready to roll, I turned the key and imagine that.... the CEL was gone. I never made it home last night to check to see if a leaky or loose cap could cause a 171/174, but it went all last night without coming back on. Anyone know if a cap issue can cause these or if it throws a different code altogether?
