Im going to start by saying i drive a 2002 with 24xxx miles and its completely stock.
i was driving down the street and my left fender liner being extremely loose got cought between the tire and the road and came completely off, exposing the whole left front side of the car. I noticed that the car started to make a tapping or clicking sound(very rapid clicks) but this was seldom. The car starts to make the noise more when its cold and especially when i vtec in the cold, which i dont think should be too much of a problem. I took the car to Four Star and they took it for a spin and the car didnt make the sound til we got back and the sound only happened when we first pulled back in. We took it for another spin with yet another technician and no sound. They said it was probably a relay on the air pump which happens to be located on the front left side of the car just behind the bumper. Well last night i was rolling around town with justin and i vtec'd a little bit and it was fine then i did it again and the clicking was so loud i couldnt hear his exhaust(invidia for those who dont know)while parked right next to him. i then proceeded to accelerate from a stop and went to about 6.5k and it hesitated a bit then kinda picked up and went then hesitated again so i stopped vtec'ing. i dont know why its doing it, or what caused it. IF ANYONE KNOWS WHY OR HOW I HAVE THIS PROBLEM PLEASE HELP!!!!!!

 

I know something makes noise when the car is cold. dunno what its called but STOP reVINg the CAR WHEN ITS COLD!!!. don't ever vtec until you see at least three bars....

Might wanna perform a compression test..

 

i never rev the car when its cold besides when im driving. i dont enter vtec until 3 bars are present and then some. so the car is completely warmed up before i enter vtec.

 

....... .....
r u kidding??? i dont even think about vtec until 3 bars + few more min....


ur engine =

 

i know. im not that stupid. i have never attempted to vtec before 3 bars! read the post before------------>>>

I agree compression test your car first then go from there.

 

the exhaust cooling makes a clicking noise not louder than an invidia exhaust though

 

But it does start cooling enough to click when driving specially when hitting VTEC.......
