i have a 1994 chevy s10 blazer 4.3 engine 4x4.. it runs really rough and for awhile i had no real power when i stepped on the gas...and when i reached 15 mph i had to let off the gas so the car would switch into the next gear and again at about 30. so i changed the throttle sensor but now it wont change gears like it use to now it revs up real high till like about 21mph then jerks into gear and again at 43mph. and if i let off the gas when its at like 3 and a half rpms its drops down but then when i give it gas again it shoots right back up till it gets to wear its wants to switch. i feel like im gonna blow my engine and waste a ton of gas till i fix it... i think it may be a sensor since it started to happen right after i replaced the throttle sensor but it could be anything.. can you help??
