Hey guys today i had trouble getting my car into gear after turning it on, and my clutch pedal seemed to go straight to the floor. i pumped it a few times and was finally able to put it into gear. But about 5 min ago i tried the same trick and just didnt seem to work it went straight to the floor i was out pumpin it for a couple minutes and finally gave up. Possible problems air in clutch master cylinder? Help on what and where to check thank you.
