I have a 97 Dodge Avenger 2.0 thats clutch was replaced 25,000 miles ago and now I need to adjust the clutch pedal, because it goes to the floor without completely disengaging over half of the time. when it is in reverse It starts to move on its own without releasing the clutch . S.O.S.!! Please Help!!!

Check your clutch fluid level, sometimes a seperate reservoir (drivers side on firewall), some clutch systems take fluid from the brake system (check brake fluid). If thats ok then the clutch slave may be failing.
If the clutch fluid is low refill it and check for leaks (or just wait till the symptom comes back). If it's happens often then theres a leak in the line or the slave somewhere.

at a minimum the pressure plate but not changing everything while in there would be silly

SOURCE: Clutch pedal won't disengage clutch

make sure fluid is full... then pump the pedal with it NOT RUNNING as many times really fast as you can.. try it after that, if it works then you need either a clutch MASTER cyliner and/or a SLAVE cylinder.. MOST likely being the slave cylinder. if the pumping action doesnt cause it to disengage then you have a burnt out clutch. The system is hydralic and takes regular DOT3 brake fluid in the small resevoir under the hood next to the brake master cylinder...
The slave cylinder being bad would mean you have to removed the transmission and install a new slave cylinder... thats the most common issue with those around that mileage...

sounds like your brake cable has broken or there is something damaged in the pedal assembly.........try pulling on the release handle and move the e-brake pedal back to its off position by hand at the same time.(you may have to tie it in this position to keep it up)If that doesnt work there is a sensor on the pedal assembly that you should be able to bypass by either disconecting the wire(1 wire system) or connecting the two wires together (2 wire system)Especially if your truck is a standard the e-brake is an important safety feature,so if these steps fix the light and dinging problem you should still take the steps to have it repaired.
hope this helps.........Good Luck!

SOURCE: clutch pedal stays on floor when released

check the helper spring on the clutch pedal. You'll have to get down in the driver's footwell and using a flashlight look at the mechanism while you push the pedal down (and pull up). If the spring isn't missing or broken and everything looks okay, then change the clutch master cylinder. The piston in the cylinder is probably binding due to corrosion in the bore. I have an 1986 and had the same problem. Changing the clutch master cylinder fixed it.
