ok when my car is just idling a 800 rpms. and if u go to the back of thecar at the exhaust u hear a slight popping noise coming out of the muffler. now what is causing that. the car is the 1 in my sig. and also i started noticing at between 3000 and 4000 rpms when i am cruising on the road or on the freeway that in between that rpm the car seems to hesitate a little and my intake air seems to get louder like a all most whistle sound that i can hear on the freeway.
ok and i have no check engine light and i run rc 310 injectors and a msd digital 6 ignition w/ coil and my fuel pressure is set at 55 psi and i use a octane rating of 93
the only thing that i can think of is the dizzy might be going bad

 

Mine does this too... hmmmmmmm..only at idle.

 

did u ever try to fix it

 

bump for some help

 

Why such large injectors? and why is the fuel pressure so high? Is this a stock honda ECU? What engine management system are you using? Sounds to me as uif you may be running super rich at idle and lower rpms. Does the exhuast smell like fuel. Becareful you could be washing out your rings

 

I have stock injectors and rail, and this was happening only after i installed my aftermarket intake manifold. I replaced my 02 sensor, and it stopped doing it for awhile, now it does it again.

 

yeah my fuelpressure use to be set at 45 psi before i got the head ported so i am going to try that again but my ecu is a sk2 p28
