I just drove ~1,000 miles this weekend including some crazy off road stuff - not a hiccup all weekend.

'03 w/ 44,000 miles.

 

my disco allways maxes out at 70 lol

 

Randy, you need to do something with your truck if 70 MPH is all she has got. With my 4:11 gears and all the mods I have made on my 99 D2 I can still hit 100 on a level road.
What up with yours?

Sledmaker,
You have an unusual issue going on with your truck, I don't see how the sun roof/ window positions can have any effect on the engine management. I would like to give you some feed back and I am drawing a blank.

Could be the fuel filter, since you're @ 65 with not much drag, then the windows being opened introduce a lot of drag, which puts more load on the engine to maintain the speed, which means more fuel is required, but if the fuel filter is clogged fuel can't be delivered properly, then the engine dies. Just a guess, & a cheap possible fix so if you haven't replaced the filter then that might be a good thing to start with...

Best of luck!

mike, its an 03 standard Disco XS. on the motorway, flat, level ground, at around 70 the revs are high and you can tell shes struggling. i expect it would reach 75-80 if pushed hard enough. any thoughts ?

 

Hello,

Pardon me if I budge into this one. I'm in the market for 2003 Disco SE and alarmed to have read that 70mph is the max speed on this vehicle? Is my interpretation of what I've been reading incorrect?

 

There must be something wrong with Randy;s Dicsco. Just about 2 weeks ago I was down south in Mexico I had my 2000 with 111K miles showing 115 MPH. [sm=smokin.gif]

 

My 03 SE will cruise at 100 easy - it's tough on gas though.

Cruises at 85-90 and gets 15 MPG.
