Chevy Blazer P101 code
 

chevy blazer ls 2 door 2 wheel automatic4.3 l v6 vortec.
i have changed the cat muffler throttle positionsensor, fuel pump 02 censors alternator battery cap rotor spark plugs and wires. i have read your past posts reguarding the egr valve and was wondering why i dont appear to have one and if that was what is supposedly throwing the code.. the egr valve is in none of the areas described in the past posts. washoping it isnt my spider and cpi hoses. the engine is running like its starving for something but cant pin point what . it spits and sputters when it feels like it. when i pull out from my drive , and as it shifts it self on to 2nd the ck engine light comes on. I only use 93 gas in it . im very close to seafoaming it. frazzled please help me .

If the code you are getting is a P0101 then that is related to the MAF sensor going bad.

P0101 Trouble Code - Mass Air Flow (MAF) Circuit Range/Performance Problem

You can try cleaning it and see if it helps any.

Thanks for the reply. Since I first posted I have seafoamed the truck. Found that my engine has no egr valve and racing cams in it and the MAF sensor has nothing wrong with it it was being picky on what gas it has to have and flashing that code because it felt as if it was starving. Happy driving.
