So i just got a 1995 ls 5 speed teg with a type r transmission it was originaly a automatic 2 owners before me and they converted it into a straight drive and some times when I start it once I get up to about 25 rpms it starts not wanting kinda like the gas pedal ain't giving it no gas then it will kinda jump and take off it does it thru like 2nd and 3rd and then that's usually when I cut it off and cut it right back on and that seems to fix the problem does anyone know what this could be?
