So earlier in the day, under acceleration, i thought i felt my clutch slip a little. Then, on my way home, my power delivery became very sporadic. i would lose power to the wheels, but sometimes my revs would drop to 0 and sometimes they would spike slightly, but not as if the motor wasn't under load. Any help would be appreciated. Oh, btw...I'm running a L18 with a 5 speed dogleg tranny and (i believe) a stock dif.
