The clutch sticks to floor at times

Hi and thanks for using 2CarPros. Com. Based on the mileage and since it happens to both pedals, I suspect the pedal bushings are worm. They are located where the pedals attach under the dash. Here are the directions for replacing them specific to your vehicle. NOTE: the item numbers correlate with the picture I have attached. I feel if you inspect item 3, you will find it to be worn and causing drag.

Item Part Number Description
1. Brake Booster
2. 353574-S36M Washer
3. 2461 Brake and Clutch Pedal Bushing
4. 97414-S Retaining Ring
5. 2455 Brake Pedal
6. 519 Clutch Pedal

Remove the hairpin clip, slide the stoplight switch, the push rod, the nylon washer and brake master cylinder push rod bushing away from the brake pedal.
Remove the brake master cylinder push rod spacer (2B129) and then the stoplight switch by sliding stoplight switch up or down.
NOTE: Since the switch side plate nearest the brake pedal is slotted it is not necessary to remove the vacuum booster input rod and one brake master cylinder push rod bushing from the brake pedal.
