Hi Folks, my disco still isn't running right- misses like crazy on the highway, but only intermittently. I think it may be the VSS, but the check engine light hasn't come on! Does a bad VSS have a code? How much is a new sensor? Should I have one installed anyway? I'm taking it out on the interstate this morning with some kind of setup rigged into the engine by my mechanic- I have to press a button when she acts up. Of course, he ran it yesterday and it ran fine- typical. I'll let you know what happens! Cheers, Paul. | ||

Sounds like a road speed sensor to me. I had to have mine replaced. About $50 or so dollars for the parts plus labor. If I were you I would do it myself. Motor Cars Ltd(LR & Jaguar Shop) here in Houston misdiagnosed the problem. Said I needed to have a valve job at a cost of $1,800.00!!! I decided to take it to the dealer. It was the road speed sensor. I truly believe when you take your LR to the dealer you will probably pay a little more but you are paying for the package deal, i.e. trained service technicians, computers, the works. And its all guaranteed! Good luck, John | ||

When did you replace your fuel filter last? It could getting be clogged. I had a similar problem. It would run fine for hours and then the engine would slow down like it was loosing power. It felt like a total loss of spark, not a misfire and then it would speed back up. It would happen at different speeds, but mostly above 45 mph and with different levels of fuel (3/4 full and 1/4 full). The slowdown would only last a few seconds and then it would speed right back up. Maybe 3 seconds on, three seconds off. Each time the problem went away if I pulled over and refilled the gas tank. However, I do not think that it was fuel related. According to the dealership, they look at 1.) Fuel Filter, 2.) VSS, and 3.) pull the heads to diagnose the problem. I did number 1 and 2 hoping to prevent #3. When I pulled the VSS (Vehicle Speed Sensor), I found that it was caked with dirt. I replaced it and my fuel filter at the same time. No more problems, but I've only driven it a few miles since the change. I followed the directions in the Tech section on the web to replace the VSS. Thanks, Mike B. | ||

Thanks for the suggestions. I am really hoping it doesn't need a valve adjust! The fuel filter was replaced last week, so I'm hoping it is the VSS. I was quoted $120 though! Cheers, Paul. | ||

Hi Guys, I got my VSS swapped out last Friday- then a friend took the rig over to Portland (OR) and it ran fine. I then took it over to the coast and back- not only ran great, but got 18.3 Mpg! The VSS was $122.50, plus $60 install. Cheers, Paul. | ||

Just had similar problems with my '97 XD. I did get a check engine light and it read out as a missfire. I ordered the VSS form Rovers North to the tune of $90 something for the OEM parts. Have not yet installed it, but understand it is not the complicated. There is a good discription of how to do it on the Tech Page. | ||

Eric, I had mine installed by my mechanic, but wish I'd known about Rovers North! I did get a code saying random misfire, but had the code reset, and the problem persisted without the code reappearing. Hope your rover is soon running as smoothly as mine! Cheers, Paul. |
