Sup guy I got this b18c R motor in my teggy and it runs great pulls hard VTEC kicks hard. But at idle the exhaust has this pop that can actually be felt in the car. It doesn't move the RPMs at all it stays 700-800 never jumps.
I posted a video on YouTube link is below. If anyone has any idea why it pops I'd appreciate all ideas and any info.

POPPING NOISE INTEGRA HELP!!: http://youtu.be/iMzAP0azHJE

 

Saw your post on my thread, looks like your car is doing the exact same thing mine was doing. It doesn't sound like you have tested anything, so there are so many things that will cause this that you will have to check. It's looking like the cause of my problem is a bad fuel injector, so see if you can swap your injectors with someone and it may fix your problem.

From my understanding, this problem is a lean misfire at idle. For some reason, the engine is randomly missing at idle because either the mix is too lean or it's not getting strong spark. The "pop" out of the exhaust is the unburned fuel igniting when it gets released into the hot exhaust manifold.

Is your check engine light on? Have you checked the basic stuff that might cause this? (spark plug gaps, cap/rotor in good shape, plug wires, compression test, ignition timing, valve clearance checked etc)

Read my first post and go through the list of things I checked, but if you can just swap injectors with someone with a good running engine I would start with that.

 

Hey man thanks for the reply. I've done the timing and spark plugs and dizzy check. Next ill try the injectors.
No CEL. Car runs strong just idles odd..

 

check mechanical timing
