Camaro94SS

SO i got my car takin in for a tuneup and i guess it still needs an air pump...can anyone tell me what an air pump does? Also...my fuel gauge is wack as hell,floating from Full fuel all the way to E all the time and sometimes gonig PAST the Full fuel line lol....the oil pressure gauge also floats a lot also,from like above half to under a quarter....but my main question is What does an air pump do?(somethnig to do with engine) =\ Help me out please! Thanks!

the a.i.r. pump pumps fresh air into the exhaust to lower the emissions

I've heard it only runs for a few seconds at startup. I took mine out rather than fix it. The car runs fine and I have enough room to change the plugs from the top now.

If you have emissions testing, I'd get it fixed though.

is the air pump, aka smog pump? and if it is,i heard that removing the smog pump gives you more a tad more HP....my friends dad remove teh smog pump on his vet and he says it gains like 6hp...???

I dont think you will see a 6hp gain from it, My main reason for removing the system was loosing my cats w/ my non emissions headers...plus it cleans up the engine alot

i have hella black exhaust tips,and theyre supposed to be chrome...its cover completely in carbon....supposed to be chrome and its solid black lol....could smog pump help that or does that involve the pump?

smog pump really is there to help heat up the cat. the impalla ss had a recall that actually removed the smog pump, not sure why they didnt do that on the f-body.

are you getting an ses light?

Camaro94SS

yeah the check engine light is on, and the GM dealer told me thats what is seting the SES light off....they said i need a new one,should i just remove the damn thing instead and save me money? If there was a recall on the impala,why not the f-body...and like i said, my friends dad removed the smog pump on his vette...so should i just remove it instead of spending like 300$ on a new one?

blkchevyz

i just un hooked the connection to mine, and then made sure the air pump fuse was still good and i never got an ses light.


mine was bad and would pop the fuse every few days.

Camaro94SS

well ill prorbably remove it,cause isnt it only for emissions and cleaner air and polution reasons...? I'm pretty sure its illegal to not have one or if you dont have one and get emission tested you will fial the emissions test because of not having it...but im not totaly sure on what the function of the smog pump is? Can anyone tell me?

blkchevyz

not having it isnt going to make you fail emissions, its only used when the car is cold and at idle/low rpm. i guess you can fail the visual inspection, but i dout they even know where its suppose to be, let alone able to see it.

its purpose is to aid in heating the cat

Camaro94SS

ok...so removing it would be worse for my engine,but not bad for it,yet still worse?

blkchevyz

not going to hurt the engine at all... the catalitic converter just doesnt work well till they are warm, so if its bad for anything its the enviroment... but thats just till it gets up to working temp witch it can still do without an air pump.

Camaro94SS

oooooooo got yah,yeah so the smog doesnt affect the engines performance at all really,just helps the environment lol...i think im just gonna remove the damn thing as a whole
