where is my getty up?

[James Fulcher]

Over the past few months I have noticed my 95 discovery loosing its power. When I push on the gas nothing really happens. The tach doesnt raise nor do I seem to go any faster. I have even noticed that I am loosing speed when going over bridges. It appears to be shifting normaly. Any advise would be greatly appreciated. Thanks

Any mods, such as a lift, bigger tires, etc? These only add weight to your already heavy/slow Rover.
Minor work such as a tune-up and a couple runs of sea-foam might cure your lag.

Let's see what others have to say...

I agree w/ what adrian said, some seafoam and a tune up could go a long way.

As far as additives, i use this stuff and it seems to do a great job of cleaning the system out, mine got a little laggy and this stuff helped out

Do you know where you can get seafoam? Is it available in CA?

I usually buy Seafoam at the local NAPA.

If you are losing that much power, and you have even done basic upkeep on your Disco. (plugs, wires, air filter, cap, rotor button).

Then I would say your cats are getting clogged and need replaced.

Thanks for the info. I have resently changed the plugs, wires, cap, etc but I may need a tune up. I will try the seafoam though. Thanks agian for the help.

Seafoam, however I typically buy mine at my local autoparts store (Advanced Auto).

I've used BG44K over the years and it works. Do a search on it and you will find many clubs recommend it. Most local auto parts stores carry it.

Fuel filter

no one mentioned fuel filter??

my gas mileage goes up

my power goes down

fuel filter time.

 

[Reed]

I'll second checking the fuel filter. If it hasn't been changed and is really plugged up it can play Hell with your power. Just not getting enough gas. You might also want to check the fuel pump. (That is what plugged up my fuel filter the last time. ) ) Checking the fuel pressure at the rail isn't a big deal and can tell you alot.

 

[barefoot]

how do you check the fuel pressure at the rail? what tool do you need and where is the nipple or whatever?

 

[bazzle]

There is an outlet on RH rail that looks like a tyre valve. I check my pressure there with a tyre gauge.

I found a TSB on this very symptom

Check your private Messages. I sent it there.

 

[James Fulcher]

Thanks for all of the great ideas. I ran a can of seafoam through her and have changed the fuel filter and it has made a big differance.

Hey, I just thought of something.

Is your vacuum advance working?

It is a 95, so its a 3.9. When the advance gets stuck, the power really suffers.

You can confirm this by checking your timing, at idle.

Disconnect the hose that goes from your throttle plate to the distributor.

Dont worry about plugging the nipple on the plenuim. It's cut off by the throttle plate. That nipple only gets vacuum when the throttle is opened.

Apply vaccum to the hose, and the timing should move....I use a vacuum pump, and wtach the timing with a light while i pump it.

I have the spec at work, but really, ifyou see some change, it's likely working. Usually, when they go bad, vacuum has no change.

Chris,

Could you send me the information about the TSB to me as well?

Thanks!
