twas driving home, not ragging or anything.and had to stop at some lights, for some reason my revs wouldnt drop and were really high, so much so that when i attempted to turn the car off to restart it even with the key out it wouldnt die properly, i had to stall it to stop it, then by the time i got home it was fine again...... is this the choke or something els, im allready aware that my stupid automatic choke doesnt work anyway but its never done that before, i want a manuel choke
