Bubb Rubb?


Does it only do it while in gear or can you hear it while coasting in neutral?

sorry about no to maybe details... i was posting this from my phone..
91 civic zc sohc stock air box.. and fram filter it just started this.. and it kinda sounds like its under the dash somewhere?
i bought the car from a kid that "tried" to wiretuck it and i have been routing wires and vac line and trying to get them in the right spot..
if i give it a little gas on the highway i can hear it. if i give more gas it goes away. and then also when i let off the gas it goes away as well..

there should be a little screw on the throttle body unscrew that a little fixed my whistling problem

Throttle body spacers make a whistling noise sometimes. You have one of those installed?

killa69er

no tb spacer as i said sounds like inside the car? under the dash or near the cluster

Unscrew the screw on the throttle body a little bit and that should fix it. But if it doesnt start checking for vacume leaks

it's probably your intake mine did it on my GSR and my prelude does it too. With no intake on the throttle body it still whistles
