    Discovery V8i (3.9 EFi) - Overfuelling

    Guys, Final (Hopefully) Progress Report After I'd Whipped out the Bypass Air Valve (Haynes Description) or the Idle Control Valve (LR Description) at the rear of the Plenum Chamber, (it was black as the ace of spades, all sooted up) and cleaning it with Carb Cleaner I have had no further...

    Discovery V8i (3.9 EFi) - Overfuelling

    Guys, Progress Report Whipped out the Bypass Air Valve (Haynes Description) or the Idle Control Valve (LR Description) at the rear of the Plenum Chamber, and it was black as the ace of spades, all sooted up, and looked like it wasn't seating. I took off the whole assembly and checked the...

    Discovery V8i (3.9 EFi) - Overfuelling

    ch427, Thanks for that, useful websites! The first one even had a guys with the same problem as me! I had a good read through Haynes, and, in addition to your own and Heyyouitsme's advice (vacuum sensor) I'm going to take a look at the By-Pass Air Valve at the rear of the plenum chamber...

    Discovery V8i (3.9 EFi) - Overfuelling

    jonnyfishing. The next place to look seems to be the Coolant and the Vacuum Sensors, if they're not too pricey it might be beeter for me to but them and change them out one by one, than pay the garage to do it. But there should be some form of test spec for a sensor that can be performed...

    Discovery V8i (3.9 EFi) - Overfuelling

    Heyyouitsme & ch427, Thanks for the replies. I stopped by my local Land Rover dealer yesterday, to be fair they were pretty good, and honest, and said their diagnostics were just the same as the specialist (they knew them well), and they'ed do just the same things, but start again from...

    Discovery V8i (3.9 EFi) - Overfuelling

    This is a PS. The '4x4 specialist' diagnostic oddly showed that although overfuelling it was withing limits and pass an MOT, also that the overfuelling seemed to be in the lower rev range. Hope that helps

    Discovery V8i (3.9 EFi) - Overfuelling

    Help! My Disco's V8 has turned into a fuel pump. It startered running lumpy at low revs, woudn't pick up from tick-over very well and started to stall now and again - it also had a slight misfire at around 2,000-2,500 revs. Its been to a 4x4 specialist and put on, what looked like to me...

    V8 Discovery - Suddenly Running Lumpy & Changing Autobox

    Jazee, Thanks for that tip. Sounds messy. I guess the sump pan will be obvious from underneath. I just didn't want to go undoing bolts and go-wheels came falling out. Cheers, Ian

    V8 Discovery - Suddenly Running Lumpy & Changing Autobox

    Davieboy, Thanks for the tip, about Brake Cleaner. I actually picked up you post after I'd had a though along the lines of "wouldn't carb cleaner be better" and bought a can of the Wynns stuff today Yes, it does have a dip stick, so I'll have a good look for the drain plug. Haynes says...

    V8 Discovery - Suddenly Running Lumpy & Changing Autobox

    Neo, Cheers for that. Not come across 'Brake Cleaner' is it similar to Meths i.e cleans and evaporates without any residue - got pints of that in the drinks cupboard. There's plenty of bolts on the bottom of the auto box that could be drain plugs, hopefully someone else might know...

    V8 Discovery - Suddenly Running Lumpy & Changing Autobox

    Hi, Last time I used this site, the help and assistance was blinding, so fingers crossed. 1) Lumpy running. Last week, after prolonged standing in stop-start traffic at the Blackwell Tunnel, my V8 Disco (3.9 EFi) started to cough and splutter on tick-over. With this being an Auto too, you...

    Djinn, Thanks for that, nice to know I'm not the only poor s*d who's had to deal with this, but didn't thinlo I was! I did a complete tune, changed plug leads, dizzy cap and rotor too, as well as setting the timing correctly, (the problem was ther before the tune). Only thing I didn't change...

    Land Rover Discovery 3.9V8i - Stalling - Fuel Filter?

    Tarquin, Thanks for that. The fuel filter is in-line just under the off-side wheel arch. Yes, the idea of chopping the flexi-tube and fitting a new union/flexi tube connector and making good with a shot bit of pipe and jubilee clips came to me down the pub last night. I just wasn't...
