Love this disco but man it is a tempermental b. Here is my new problem for this disco II. She starts up great and runs nice for until she gets warm then she starts sputtering at cruise speed, but when i give her some gas she wakes up and then sputters again at cruising speed. I am hoping a fuel filter or pump? I am not going to the dealership they will probably try to sell me a new gas tank....... Any info would be great this forum rocks.

 

That definitely sounds like a fuel delivery problem. First off what year, how many miles and has it thrown any codes? Any lights on the dash?

 

how often do the TB sensors get funky on these rigs?

 

It is a 2000 and i just had the whole engine ran through spark plugs, fluids, hoses. I have not had any codes run on it yet and there are no lights on the dash

 

based on the info and my experience on past vehicles,

it sounds like a fuel issue. either a clogged filter or a pump going. my money is on the pump.

 

I hope your right that sounds fairly inexpensive any experience installing one on a disco.

 

last pump i changed was on my dads truck. required lifting the bed from the frame.

but if i am betting you can gain access to the pump from under the rear cargo area. under the cargo mat.

give it a lift and check it out.

 

Sorry I don't have the pics from the RAVE but...

Do you have any fault codes? It is not a fuel filter, your truck doesn't have one.
How many miles on the engine, did you replace the plug wires also, how about the 02 sensors, have they been replaced, whaty octane gas are you using?

 

Great post!!!
