I've just purchased a cold air intake off E-bay...Nothing fancy, just the intake. My question is, do I have to adjust the timing now that it's getting more air? This is the first mod that I've accomplished, and the engine is pulsating from 1000 rpm's to 1,300. The 2 vacuum lines are correct, but it seems that the e.g.r valve is pulsating consistently, unless I restrict the volume of air with my hand....Then it drops down to 1000. What's going on??? Please help.
Thanks,

no you dont need to adavance timing, and you have a vacum leak..

 

Thanks for the reply. If I have a v. leak, why wouldn't it have done the same with the oem air filter in place? And where should I start to solve the problem.
Thanks again.

 

look on the back of the intake manifold

 

when u removed the intake u might have not blocked off the vacuum line that went to the intake. look for that u can by a set of plugs from autobarn or some **** for cheap

 

a vacum hose might have ripped or something...just look...i bet there is one.

 

does sound like a leak

 

The thin line that I believe you are referring too.....I just connected it to the smallest line input that it had on the pipe.
The intake had two areas for the lines, so I just copied the transfer to both of the lines.
It runs fine now, it's just that the rpm increase threw me for a loop. It hiked up to around 1,200 to 1,300 constantly. I took it off and installed the original, and it quit.
I assumed that the air had dramatically increased (as it's suppose to) and boosted the idle, so I adjusted the idle screw, and it smoothed right out. It stopped pulsating.
Now..... if I crank it up, and punch the gas (which I know not to do) without the engine getting to operating temp. it will do it. I'm thinking that it didn't have time to lean out, and like I said, I thought it was getting to much air. She seems to be doing fine, now that I've adjusted the idle screw. Even if it seems to be running fine, is there still a chance that something may still be wrong? I checked all of the lines, and I didn't find anything missing or split.
Thanks man,

Sounds like you didn't cap the open nipples on your intake manifold after you ripped out the old vaccuum lines.

 

Nope.....I didn't know that I was suppose too. Did that confuse the computer in some way? Never mind, I guess it confused something......It lost suction/pressure. Right?
Anyway, all seems well......for now.
Thanks a bunch guys,

Man, it's not getting any more air than stock. An intake doesn't really do anything... Definately don't worry about your timing.

and it sounds cooler.

Well with a sri you can suck up hot air into your engine. With a cai you can suck up water.

 

arc air box FTW

LOL dramatically. hehehe we all wish that would be the case.

Double check all your vacuum lines again and reset your ECU too.

 

Is the injen sr intake any good. Anyone heard good or bad about it? Is it going to suck in crap into my engine that shouldn't be there? thanks

 

An intake adds anywhere from 1 to 3 whp on a stock prelude.

 

i'd say an ebay cai ($20 or so) with a k&n 4" inlet canister type filter (80$ one) with 3-4" adapter, you'd get maybe 5 whp. still worth the +/-100 bucks you'd spend.

 

i was looking at this thread, thinking, i don't remember creating this lol

yeah if empty wallets and no power is cool these days.

but hey at least the jdm chicks love arc stuff.

 

^ lmao
