NELRC Vermont Expedtion - 9/12/14 - 9/14/14

I'm down I'll bring a tent just in case. So e one had to let me know what's going on the. For the extension. I do t think I can do before since I already put in for that Friday.
(201) 776-123six. Call/text me

maybe the extension isn't going to work… i don't think i can do after.

here is the current map. Blue is day 1 red is day 2.

I cannot do after we have to be back Sunday nite wife has a test Monday for school

We can maybe do 1 or 2 days prior, my rover is acting up and need to figure out the p1179 or the trip is a wash for us

Just when all was going good the rover gods have rained on my parade

Stolen from another Rover site, with good explanation of code.Ok, I know this may sound strange but here goes: Not everything said is gospel, mine runs on ~25psi fuel pressure, ~35psi engine off.

P1179 - Maximum Negative AMFR Correction Fault

What is this telling you? P1179 means "long term fuel trim too rich, banks 1&2 (AMFR)." OK, so what does that mean? It means the O2(s) are telling the computer that it/they sense there is too much oxygen in the exhaust so the computer is attempting to compensate by telling the injectors to stay open longer each cycle so that the fuel/air mixture is correct; however, the computer has now reached the limits of the set parameters for the amount of fuel the factory believes your engine needs to run, hence "long term fuel trim too rich." Basically there is a window of too rich (P1179) and too lean (P1178). What causes this? Well several things and one of the worse things you can do is throw money at parts without taking the time to diagnose (you or your mechanic).

Here are a few items that can cause the computer to want to richen the fuel mixture:
O2(s) – dirty or bad
MAFS – dirty or bad
Low fuel pressure
Vacuum leak

In your shoes I would have checked my fuel pressure at the rail first. If the fuel pressure is too low then your injectors cannot squirt enough fuel into the cylinder during each cycle. The O2s sense this lean mixture by noting the higher than allowable level of oxygen in the exhaust and send the message to the computer. The computer tries to fix this by telling the fuel injectors to stay open longer, but eventually they can stay open only so long and your computer notes the fact that it can no longer match the level of fuel needed, so it logs P1179. If it does this two trips in a row it makes the little dash light turn on.

There is also the chance it could be a leak in the vacuum lines or a valve cover gasket for instance and the engine could actually be bringing in unreported air (air that the MAFS cannot account for).

You can get the same code from a bad O2 that sends the wrong information as well as a MAFS that tells the computer more air is coming into the engine than what really is.

With P1179 I would have checked fuel pressure and for a vacuum leak before moving to O2(s) or MAFS.

Go get a fuel pressure gauge for your tool box (less $ than taking it in and having it read by a mechanic) and let us know what it reads – should be in the 34psi to 36psi range. If this is good then start looking for a vacuum leak.

Hope this helps, Good luck, and report back.

-B

O2 were replaced previously, tried changing MAF with 2 others I have, no change to readings on the ug

I am away working so will check fuel press when I get back, I think this is the end result of my complaints on the rausch trip of my d1 having no power on the road and slowing on inclines on road

Hope it is just the fuel pump


Thanks for the info

Randy at rover bones just gave me the heads up it's done it still needs work but closer from where it started. really pushing for it to go to VT.

Fern, it looks like you need a rear bumper more than a front one.

Dan make me one I'll buy it off you with rear seats then you can sell the one you have now.

If you want rear jumps I got a pair with seat belts, only mount brackets for 1 side though

I have the seats, belts and brackets for both sides of a non rear AC Disco.
I also have a factory rear bumper in much better shape than what is on Fern's Disco today.

I'm heading out Tuesday night or Wednesday morning. Going to do some fishing and whatever other adventures I might find. Cape Cod for a day maybe. Anyone else wants to join me give me a shout! 858-357-1465.

Unless I can fix this 1179 we will not be able to attend not happy

Here is a shot of the stock rear bumper I have. Fern should buy this one too..........
It has a good dent in it and the lenses ae\re ok, the lens mounting tabs are not in great shape but functional.

Coming up so what's the plan. ?

Bring warm clothes, overnight lows are forecast in the 40's all this week.
Should be nice weather otherwise.

$22 bucks a night for a tent site? Was the Waldorf booked for the night or something?

LOL there was nothing else around. the state parks require multiple night stays so those are out of the question.

This trip looks very interesting so I will be coming over from Michigan thru Canada.

Ed, do I need to make a reservation for Friday night at that campground or can I just show up?

Also, looking for recommendations, for either a good campground or Motel around Lake Champlain for Thursday night.

One more question: Looking some interesting  things do or see in VT on Friday morning or afternoon.

Heather

hey heather, not sure about just showing up. i think you may have to book ahead. i asked around to the vermont rover people and they said "to stay in Manchester or at the Upper Pass Lodge in Londonderry, both on the way"

Sucks we may not make it, have no one to watch our 19 year old dog and have to get the lr3 shipped up

ah that sucks Tom. i know the feeling though, my parents just put down their 15 year old dog and now they are a bunch of travelling fools. Ryan is heading up I was going to suggest you convoy up with him. Vermont is some really good wheeling and I think you would have enjoyed it, not so much breaking your truck on rocks, but challenging off camber stuff and great scenery, you can always hit up next years expedition trip. Hope to see you at Rovers on the Rocks.

Yeah we really wanted to go,bought the new tent and everything, also my steering is still bent up waiting on the tube adapters to Fab new steering

Plus if I get the shipping going on this lr3 I can't depend on anyone here to take delivery, god forbid it gets messed up like bretts

So who's all going and when are you getting there? I'll be up at the campsite around 5 to set up while it's light still...then in for dinner.

. Sup?
