Ok, Ever since yesterday it seems my car takes full throttle to take off smoothly and I have to ride the clutch without the car starting to vibrate like it is going to stall. I don't know what it could be but the throttle doesn't seem as responsive. I've always had to floor it to get it to the speed I want without taking forever but this is a lot different. Lately I've been letting my girlfriend drive my car to teach her how to drive stick and she stalls a lot and is very very jerky on take offs. She has also grinded my gears like twice, but hey, that's not too bad considering I've made a few mistakes like that once or twice. But again I noticed that if I don't give a crap load of gas and ride the clutch the car has like no power and feels like it might stall although I haven't yet. Has anyone had this kind of problem with their focus? And what you did to fix it? Thanks.
