i have a 98 rs coupe, and for some reason, when the ac is on, it makes a blow off sound when i shift gears. does anyone know what this is, or why this happens?thanks

 

Good luck.

I have this same issue with my '98 LS and have asked around here and over on TI. So far, nobody has been much help. Nor have any of the troubleshooting steps from various manuals - they don't cover this symptom.

In addition, with mine, I can feel/hear it during cruising periodically also. And the A/C seems to leech more power than it should.

Hopefully somebody else that can help sees this.

 

yep i do have this same problem... mine also picks up in the powerband at 4k rpm and seems top accel. faster .. ill find out when i take the head off when my new one is built....

 

glad to know I'm not crazy...

 

ha thanks guys.i was thinking the same thing

 

i just tell people its my shitty turbo...hhahahahha JK

 

only when the ac is on it makes this sound!? i have a 98ls never had any thing like that, except one time my tranny leaked all it's fluids and it sounded like it was on a conveyour belt when i shifted... like those whistle toys at parties zzzzZZZZzzzzzzzz...

 

ok my 95 gs-r does the same thing. when my a/c is on it sounds like a coffee can on a 94 neon. good thing i don't live in a very hot place. but hopefully someone comes up with the solution.

 

haha. hopefully somone has the answer, just glad im not the only one.

 

yea im in FL and i need the AC to cool my steming hot leather seats and what not... man i wish i had the TSX A/C Seats!

I just put one on my car last week. It's not a factor. Other than that, my car is bone stock.

In my case, the noise seems to come from the driver's side towards the firewall. If I rev it up via the throttle cable with the hood up, it sounds like something is cracking somewhere in that location when the revs drop. From inside the car, it sounds kinda like a blow-off valve. But I haven't been able to pinpoint it yet.

Again - this only happens with the A/C on.

Hmm cuz i know that on my car it does that but its because of my intake.

 

Has anybody checked for leaks in the AC piping??

 

You guys are not the only ones my 99 civic does the same ****.. . sounds like some one is murdering a woman under the hood when i shift and sometimes just lettin off the gas does it. I have not found out what the problem is though

 

bump for an answer , my car does the same thing after changing the a/c belt.
