i started my car this morning and it made a loud sucking sound. so i poped the hood and it waseven louder. then my dad came over and checked my vac hoses and he took the air cleaner off and i started it and it was sucking air and it was very loud. is that a problem?

 

are you thoughing a SES light? i know when i was burning a chip once, and i got a bad burn, it threw and SES light (bad chip , so no code DOH) but the car idled at about 2k, and was really making a loud hissing/sucking sound. i think i was in limphome mode due to the bad chip.

 

no there wasnt any light, and i have the stock chip. this was the first time it ever did that. it idled normale.

 

starting up in the morning the iac typically opens up to aid in warm up and usally makes a loud sucking noise and gradually decreases as it warms up. next time it does that just put ur finger next to the hole and see if its sucking a lot of air if so stop it up for a sec or cup it and it should quite down if it does that is whats making that noise.

 

that sounds like what it was doing b/c after it warmed up ot quit but it has never done it before. and i just put a k&n open element would that make a diff. thanks

 

thats probably what it is, you are just hearing more throught the element, the factory filter housing ect, keeps the noises to a min. but if you put an open element on you will hear alot more engine noise.

 

ok but i took the element off and started it for a sec and it was still making the sucking sound and it was coming from the tbi

 

exactly, put the stock housing back on, and see if it does it. they make noise, there is 305 cubic inches trying to suck air through a little ittty bittty hole. but the stock housing acts as a muffler, so you dont' normaly hear it.

 

ok thanks i just thought somrthing was wrong b/c i have had the open element on for about a week and never heard that.

 

i had the same problem when i put my open element on, try and find a gasket to go between the base of the filter and tb, that helped mine from hissing
