lean

So my buddy was driving from MI to FL and when he filled up his car he added Fuel injector cleaner and octane boost.... not 100 miles driving he started having some rough driving and now has little to no power when trying to drive. I know what the codes are but before buying parts and jumping to...

I had posted earlier about lean codes on my '00 Explorer Sport, and fixed it easily by replacing an evap hose. Well, now P0174 (bank 2 lean) is back and I can't figure out why. It appears intermittently and only on this bank. I have done the following: -I smoke tested again, and there's no...

Howdy! I have a 2000 Ford Explorer Sport. Currently, it has a check engine light for P0171 and P0174, stating that it's running lean. I used a smoke tester and found a substantial leak-- one of the hoses is ripped apart. While running, moving the hose causes the idle to fluctuate, and a lot of...

Hi all...Im helping repair my sister-n-law's 2006 Explorer XLT 4.0 sohc v6. Its got "running lean" code and "random multiple misfire" code. Ive replaced the ignition "coil/box", intake o-rings, fuel filter, plugs and wires. It starts up just fine (when cold), then upon warming up, starts...

hey guys so i just picked up a 1998 ford explorer sport (2 door v6) 88k miles magically the CEL came on after 250 miles of driving (i know i should have checked to see if it was reset) codes were P0171 and P0174. -I ran some injector cleaner thru and dry gas as well, reset and light came back...

I have Bank #1 - Rich and Bank #2 - Lean Codes! ???? P0300, P0301, P0302, P0303, P0316 Codes were corrected by replacing the plug wires and cleaning/gapping the plugs. I have new plugs on hand and will replace them. I used to think I was fairly savvy at diagnosis, but those days are gone...

Hello Forumsurfers! I am helping a friend of mine work on a truck that he has. the truck has the following setup: 2000 Ford Explorer 4.0L Auto Trans 4x4 (Yes) Miles is ~160K I did a full tune up when he first got it, including the Plugs, and wires and checking changing most of the...

Hey Everyone, I had a recent problem that maybe someone on here could give some help with. I have a 2002 Explorer XLT, V6, with just under 180K. Problem: So about 2 weeks ago, my CEL came on. I ran the codes at Autozone and it showed P1131: Bank 1 Lean, Possible Misfire, Possible Vacuum...

Hello, just bought a 98 explorer (my third try at explorers) it has 198XXX miles. The driver side leans, I have read the other post and know that the gas tanks and driver and battery are on that side. That being said I notice by pushing on the side that the drivers side shock is much softer than...

long time lurker, first time posting. I have a 00 explorer. I'm planning on doing some exhaust work. the current state of my exhaust is poor to say the least but I'm planning on upgrading the following - New dynomax 2" y-pipe (no pre-cats)... still not entirely sure how this will work out...

I am having multiple issues with my 1997 Ford Explorer. Engine = 4.0 SOHC, Vin E. I am by no means a mechanic, but I can do my own work. When I first start the engine, the RPMs highly fluctuate, a heavy vibration, and the engine rev's on its own. I have been experiencing very low MPG and...

Hello, I've read the torsion bar 101 thread on here and it confirmed for me that cranking the bolts on the bars lowers and raises the front of the vehicle but it didn't answer one question. I just got my leafs rearched to add 2" on the left and 1 1/2" on the right. the truck still leans a little...

my 96 explorer 4.0 4wd leans to the left when looking at it from the rear. anyone know how to fix this, and whether its something small or something serious. thanks

My '94 Explorer Sport has been running rough for a while. I have cleaned the MAF sensor, replaced the plugs and wires, replaced the throttle control sensor, the idle control sensor, and I have run lots of cleaner through the fuel system. It is getting better gas mileage than I have seen in...

91 explorer eb edition, it was running allright till a week or so ago, when i would be at a stoplight it would be fine at first, then the idle would go down to 900 rpms and it would shake and act like it was gonna stall, the voltage meeter also goes way down, lights dim and whatnot, it drives...

Im running very lean, i dont know how lean...but I am. Im eventually going with a supercharger from a Nissan Frontier/Xterra. Ive already upgraded the throttle body to a 66mm, and bigger MAF housing, and CAI. So if I dont do anything about the fuel system now, im looking for trouble. As of...
