Power loss in range rover p38 4.6 lt when going up hill

When running on level it's shuddering very lightly but when climbing a hill we start to slow down it's like we are losing power but we get to the top and pick up speed

The p38 is a bit sluggish and slow on long steep hills, really not geared for performance but more as a piece of heavy equipment. strong horsepower wise very formidable powertrain but you're not going to have that get up and go that many drivers look for. couple quick suggestions you may want to check your plugs and wires a common weak spot in the ignition system, and i might suggest also running i can of seafoam through your engine. you deposit in your gas tank runs through with the half a tank of gas. i'm not a big advocate of fuel additives or octane boosters but in the case of seafoam it's definitely a worthwhile and proven product. don't forget also your sport mode button down next to your shift lever push that button down and it keeps your transmission from overdrive so you can accelerate into freeway traffic and climb hills without your transmission shifting

yeah, don't drive so fast!!!!...seriously i would do what has to be done anyway to start. change fuel filter, air filter, spark plugs, spark plug wires. these have to be done at some point if they haven't been.. if that solves your problem, if not look at fuel pump, injectors.u didn't say if it used to go faster, maybe there is a limiter.

Hi Adam,

Bring your vehicle to an auto parts or battery store. Ask if they could perform a 'Load Check' on your battery. This not only checks the voltage, but also the amps, as if it were under the load of turning your engine.

It takes a few seconds and the results are pass or fail. Fail means it's time for a new battery. Pass means we need to look elsewhere.

Comment back the results.

Hope you find this to be very helpful

The Solenoid fitted on the Steering Rack is not getting the command from The Body Control Unit. Kindly Replace your BCM and then your problem is solved. You can try to make sure by giving direct current of 12v to the solenoid and check the Steering. if it works then simply change the BCM as it's not giving d command to the Solenoid. Salman EiD

Loss of power climbing hills. Replaced the loss of power climbing hills. Replaced the transmission 2 years ago. Could it just be a dirty fuel filter or a bigger problem?

I got this, and it was a failed trans shift solenoid no 1. This rendered the trans unable to find low gears. However there should be a trouble code notified by a light on the dash.

2001 4.6 HSE range rover will not shift up until 3000 rpm will not shift into 4th gear.

I don't know the solution and I don't want $$ but have you checked all your mode switches? It sounds like you have selected hill climbing mode or something similar.

Power fadded over a few days now its dead. Fuel Pump?

It's quite possible to ruin a fuel pump by letting it run dry, especially if it already has years of use. When you first turn on the key, leave the door open and see if you can hear a high pitched whine for about three seconds. That would be the pump priming the system. If you don't hear it, then the pump isn't working. Be sure to turn the key of for about 10 seconds before you try listenng again(it has to reset). It can be hard to hear, especially over the key buzzer.
