Free flow filter causing lean codes??? help
Hey all, im new here and all that blah blah blah, anyway on to the fun stuff. I have a 97 Ranger 4.0 XLT. My problem is that as soon as i install a free flow air filter with no airbox, i get lean codes on both banks. (171 174) If i put the stock filter and housing back on and clear the codes all is well and they dont come back on. I think that maybe my MAF isnt keeping up both try as I might I cant find an aftermarkit performance MAF for my truck anywhere online. Any of yall had this problem and if so, what did you do to fix it? thanks in advance!

its just basically like a spectre or k&n free flow cotton filter. Its a no name brand but the thing is im using the stock intake tube and everything down to the MAF housing. I just put an adapter plate on the MAF housing and then the filter clamps onto that. I dont really see where i could be pulling un-metered air from.

Oh and put about 50 alternating sequenced LEDs on the filter to give Jp7 a run for his money...LOL

Yeah StxDangerRanger , thats pretty much what I said, I DIDNT put a cold air intake on because it has one stock. all i did was a free flow filter. so whats your point? And Jp7, how is it not restrictive, its like a two inch intake whole feeding like a 3-3.5 inch intake tube. I would call the restrictive.

Did you clean your MAF sensor? I had a K&N on my Ranger and 89 Mustang for a few years and noticed a build up of oily lint on the MAF. I found a few site that mention that happens, causing slow readings to the computer. I went back to pleated paper filters on both my 89 5.0 mustang and the 07 2.3 in my Ranger.

put your stock box back in and remove the silencer. opens the box right up and you wont get any codes. your workin with a v6, not a v12, either run the filter further away from the sensor, or put a proper kit on the truck. ya wanna cheap out, you gotta deal with the BS that comes from jerry-rigging the intake.

For an intake to be a cold air intake it has to draw air from somewhere outside of the engine bay, Just cause you have a free flow filter doesn't mean its a cold air intake. You can have a free flowing filter INSIDE your engine bay and its sucking hot air, defiantly NOT cai. Yeah my maf has been cleaned and besides it was an oil-less filter so it shouldn't have done that anyway haha. And what silencer are you refering too? On the '97 4.0 there isnt a silencer in the intake tube. Unless your talkin about the pathetic little twisted tube thats before the filter that pulls air from behind the bumper/headlight? I already pulled that thing

Just put down your wrenches now.
If you honestly think that a free flow air filter and a Cold air intake are different, you need to quit.
You said:
you put a free flow filter on, with no airbox. Which in its basic form, Is an air filter, on the end of a tube. attached to your upper intake.
Now, if i go to K&N and search ("filter & ranger") I get this, a FILTER ATTACHED TO A TUBE. that goes to your intake.
give it up dude.
you made a mistake, we all do. I remember when i wanted to go fast.

Ok guys, how about instead of makin a bunch of smarta** comments, why dont you EXPLAIN what your sitting here saying? I thought this forum was about ranger people getting together and HELPING each other? not being dicks about stuff like a bunch of little elemntary school kids. I mean seriously grow the hell up. 04RangerDave is the ONLY person that has bothered to make a helpful suggestion, so thank you dave for actually holding to the point of this thread and this forum.

heres a pic of some random dudes intake from another forum....
And heres what a poster said about it, QUOTE "Hot air intake for sure!! All looks, but not functional at all!"
And heres what the next guy said, QUOTE "i believe he understands its a hot air intake genius but the fact is he is still getting more air flow than the stock box."
End of story, I honestly dont know how to spell it out anymore for you guys. Its not a cai if its inside the engine bay!!! Unless your trying to make a completly different point that im missing, ( the wonders of typing compared to conversation), you are incorrect. NOW, if you still disagree with me, please EXPLAIN your point as I have.

politely as possible, yes, nominally what you have is not a 'cold air intake,' because it sucks warm engine compartment air. but dude, it's a 160hp ranger. weather or not you have a free flow filter, what you regard as a true cold air intake, or you simply modify the stock air box, it's going to be a 160ish horsepower ranger, your original question was answered to the best of their ability, they think it's unmetered air. so either ditch it completely or fix it and run it if you wish.
