ok my 1993 chevy blazer is acting a little weird...first off when im driving it starts to run the RPM's really high. and it doesnt shift out of first gear unless i take my foot off the gas and let it decelerate. when it gets more gas it doesnt do that (only on a rare occasion). also my ABS light comes on and it does something weird with the brakes like when the road gets a little bumpy and rough when im trying to brake it starts making this noise i dont know how to describe it and it kind of skips or pumps the brakes a little bit??!!
