Toyota MR2 clutch doesn’t operate well when car has been running a while?

Hello, sounds like you could have a slave cylinder or clutch master cylinder issue -- if you have verified all air is out of the lines. There could also be contaminants on the clutch disc and flywheel - but I'd think there is more likely an issue with the hydraulic system. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
