Road Trip from Philly to Mobile Al

[ThisGuyUKnow]

Having an engine cut out on an uphill grade sounds pretty serious to me, getting a lean trouble code does could be a fuel delivery issue. Having a good fuel tank vent system and making sure the fuel pickup sock is clean can be factors here. When I want to check my O2 sensor, I plug in a digital voltmeter to it and look for a .9 volt variance while driving. You really went for quite a shakedown cruise.

Shake down cruise?

I'm going to relocate the fuel pump to the gas tank in the very near future. The o2 sensor is either bad or the wiring is bad. Pretty easy to figure out with a voltmeter. The engine cutting out was certainly annoying, the problem was sparatic and I have not had it creep back driving the jeep without a trailer in tow. Like I said I think that the proximity if the pump to the exhaust while running lean under a high load is getting the undercarriage hot enough to cause issues with the fuel pump. Either the pump is over heating or the lines are vapor locking. When it happens you can tell it's just not getting enough gas to maintain the rpms at the given load. That means either bad regulator,tps,injectors,pump,or fuel lines the most likely of those being the pump or tps.

Fixing the o2 issue may solve the issue as I have isolated the pump as the fuel problem. Also moving the pump to the tank where it can be cooled by the liquid and more easily get primed will help alot as well.

Any sensor or part can potentially go bad. It's nice to have a computer that can tell you what might be wrong.

^^ Well, your posting the obvious. The computer may give possiblities. I have at code 33 (map sensor), tested, and it was working as it should turned out to be an intake manifold vacuum leak. New valley pan and TB gasket and no code 33.

Well code 33 indicated an issue with the map. The map can't read right with leaky manifolds. So the computer seems helpful to me.

Not true, cleared the code and ran it for two weeks before I had a chance to replace the intake gasket and adaptor plate to manifold gasket. Ran it another few days before I picked up a TB gasket. The code never came up again Since I cleared the code even with vacuum leaks. I did notice the vac hose from the map was close to 12" long so I took a couple inches off the length. Map vac hose shouldn't be longer then 12". Computers are helpful in pointing out the general direction of posible isusses but it typically takes further troubleshooting as well.

I'm not really sure why we are going back and forth on this, would you like me to change my original statement to it doesn't help me to have a computer to tell me what's wrong?

My original post was to Hedgehog, not sure why your quoting me.

Whooow , ah , errrrrrr , hmmmmmm - Wasn't looking to start a back and fourth kinda thing. I just didn't know what a TBS or TPS or other unknown sensor was.

Dang fangled injection stuff.
