Because I hear some kind of poping sounds. Not very loud but loud enough that you can hear it. It's mostly on 2nd and 3rd, when rpm reaches above 4000.
Could this an engine knock?

If you are sure it is a popping sound, it is probably not an engine knock. If you're talking about preignition knock, that is usually a metallic clattering sound. Take some nuts and bolts and shake them lightly in a tin can and that is the sound you will hear. If you're talking about bearing knock, that is usually a heavy thud. Can you describe the sound better? Is it dull or sharp?

If you can hear anything it's most likely not engine knock. Get under the car and have someone rev it up in neutral and try to pinpoint the spot.
It's probably a heat shield banging the manifold or the exhaust hitting something- our knock sensors are really oversensitive.AIM: escalier deverre<br />\'02 Pearl Blue Metallic RSX-S (daily driver)<br />\'98 Black Firebird<br />98 V6 turbocharged to 02 LS1 swap<br />\'02 LS1/4L60E<br />LS6 Block, LS6 Intake Manifold, Thunder Racing 215/220 .600/.523/115 Cam, Titanium Retainers, Crane Double Valve Springs, 125 shot NX Wet Kit w/ NOS brand Purge, True Dual \"H\" Pipe w/ two chambers and dumps, 17x11(rear) and 17x9.5(front) Black Powdercoated ZR1 Replicas on 315 and 275 BFGoodrich Comp T/A\'s (Street)/ET Drags/Skinnies on Weldlites(Track), 3.42/LSDComment
