Hello everybody, OK I own a 2000 civic Si. This is my story
I was coming from school and I was driving in 5th gear then I down shifted to 4th because I was dropping my speed and whenI step on the gas my RPM wouldn't pass over 4 rpms it was kind of hesitating on me. So i pulled over while engine was running I gas it hard and still wouldn't go over 4 rpm. I keep on trying that and same result. So I shut off the car turned it back on and worked fine . Then when I step on the gas NOW i get this weird whistling sound coming from the intake (AEM short ram) before I wouldn't get this sound. I only get this when I let go the gas pedal then step on it again

Any help really appreciated. Thanks

 

Anybody????[&o]

 

I have a 1992 honda civic , sometimes I got the similar problem. I changed the transmission fluid. It worked better. I am not sure this may help for you.

 

I don't know about that because my car is 5 speed. My tranny oil is much ticker compare to automatics.

 

the throttle body might have something stuck in it.

 

it looks fine i have checked it already. do you think it has to do with my Idle air control valve. My throttle plate was dirty with all this black crap. So my mechanic cleaned with carburetor cleaner then he turned on the car and gave in a couple squirts in there. He said it wouldn't hurt it. Then my rpm needle started acting up weird. He adjusted the screw on top of the throttle body and the rpm worked fine but I think my Valve might of gotten damage with that fluid

 

It's prolly carbon build up. It should cycle through and be fine. Do you notice any problems still?

 

Not today because i was driving all day my other car. it's a 94 accord ex. That is what i been thinking maybe carbon build up

 

ya its that carbon build up but ya that whistling sound is normal it does that cuz its sucking.... in air

 

quick question:
did you check the air filter to see if it is clogged up or not?
