My 2000 gmc jimmy will move real slow put the rpm's continue to rise as you press on gas pedal, then you let up off the pedal and press it again the vehicle will move normally, what would cause this?

1. The Pedal is not connected!! as there is no action it does, since you can easily start on the engine, then there is no problem with the engine itself.
2. Does the RPM moves while trying starting engine? if YES, so it is a pedal problem

Look for where the throttle cable connects at the throttle body. If you can move the throttle plate here and get the engine to respond, then the cable is either broken or disconnected at one end or the other. Any other situation doesn't seem likely.

why would you want to adjust the rod from pedal to master? Not common at all...

I would say your rpm sending unit is bad. It may just be loose. You would have to check the wires to make sure.

disconnect the throttle cable from the throttle body and try to rev the engine

if still cannot rev past 2000 then suspect MAF (mass air flow sensor) or the throttle body...remove the snorkel and check to make sure the throttle plate is moving freely

finally, if when the accelerator cable is removed and rpm's rise above 2000 then suspect the accelerator cable and/or gas pedal

down the dipstick tube!!!(really)DO NOT OVERFILL...
Your audi is fitted with a fuzzy logic gearbox, it will change according to your driving style.TRY THIS,put into 1st and without touching gas pedal, let the car accelerate to top gear,stop Then using onle 1/3rd gas pedal do it again.then using 2/3rds do it again.then only using the minimum pedal req accelerate to max legal limit.(try not to use brake pedal,let the car slow down itself,until you have to)then drive as normal, it will feel like a different car.

You could have a cloged EGR valve on the jimmy, which can be removed and cleaned with carb or injector cleaner which you can buy at any parts store.
As for the air leak on the brake system on the truck. That's bad and needs to be replaced or repaired, taking a guess that the sevice brake valve gaskets may be bad.
Good luck and hope this helps.

Replace the shift solenoids (there are two) inside the tranny, just in front of and to the right of the tranny filter.

Hi Deettec

your problem seems very easy :) hope this one work with your envoy. Just buy AC DELCO carburetor tune-up conditioner.

How you use it: engine running , AC off please

1. detached the big black airflow hose which is attached in the mannifold of the engine block.

2. ask your friend to step on the gas pedal and set the rpm steady in 2000 rpm only.

3. then spray vigorously in 8 seconds the inside circle opening of mannifold while your friend steady step on gas pedal with steady 2000 RPM only.

4. after you spray, let your freind continue on gas pedal with 2000 rpm for 15 more seconds.

5. attached back the airflow big black hose to the manifold and you are ready to roll with your AC on.
