Hi All,
I am still having the problem where my 96' Disco loses power going up long hills. I bought the OBD-2.com package and the codes it read were for misfires on #3 and #7. Since I have new plugs and wires I figured the wires needed to be routed better(farther apart). I did this and the truck runs smoother. Anyone know how to clear those codes so I know if it misfires again? Now back to the losing power... It doesn't vibrate like crazy anymore(probably misfires) but I'm not sure if its the engine or the trans. I will be driving up a long hill at speeds between 35 and 55 mph going along fine, and then It start to slow down as the hill gets a little steeper, so I give it more gas and it shifts into a lower gear, but the RPMs steadily decline even with the gas pedal to the floor. If the trans was slipping the RPMs wouldn't drop when the gas is floored, right? When this happens, I have to pull over, put the trans in N or P and then back to D and it will run fine the rest of the way up the hill. When it was in N I reved the engine a few times and it sounded fine. The engine is under a lot of load going up this steep hill for about 1.5 miles, could I be losing fuel pressure as I reach the top? I put in a new fuel filter and I am not getting any codes related to the fuel system. Please help |

Also, the truck has a new VSS which didn't make any difference. This problem has only occured on this one hill. It always happens around the same spot, which isn't even the steepest part of the hill. There are a few "S" curves and then a straight away before this spot. If the truck was carborated I would think the gas might be sloshing around in the turns. My tank is half full, so I don't think I could be starving the fuel pump. Occasionally it will make it up this hill without a problem. |

Well, I figured out how to reset the codes. The program got corrupted and I couldn't get to the lower half of the screen, where the reset button was. I think The problem with the loss in power is related to not having enough fuel. How much fuel pressure should I have? |

There was a thread on fuel pressure a few days ago that you can look up. Do a keyword search for "fuel pump" and it should be the first one from the search results. |

Brian,
Do you like the ODBII software. How is the interface? Pretty intuitive or kinda clunky?

The OBD2 software is easy to use, but there are no instructions with it and the help section is mediocre. I don't think I know all of its capabilities yet. I have tried it on two different computers. On one computer, the screen of the program doesn't open up all the way. It works fine but the reset button to clear the codes is in the part of the screen that is not there. On the other computer the program opens up fine, but it won't connect to the Rover. Go figure... |

Peak fuel pressure should be ~36-37psi. At idle with vacuum connected to pressure regulator, 30psi. |
