February 25, 201188 s10 blazer..changed fuel filter,added inject cleaner,gets fuel,spark plugs ok. ran fine for a few days,with lots of pick up, problem returned. Boggs down when press on gas, will not let me go pass 30mph even pressed to floor.when off the gas it revs slightly up and down,like it wants to go. but will run for a little while,then problem returns.Need some steps to tackle this problem.Is there a way to check if it`s a transmission problem ?

February 25, 2011I would lean towards the trans. Check the fluid and see if its low.

February 25, 2011my old blazer did something similar.mine had a heating plate under the carb that would glitch out. if i pulled over and killed it for a few min. and start up it would be fine. not sure if thats your problem but look into it.
