my car is idling bad..(not real bad though, it's just shaking when on idle) and i don't seem to know what the problem is.. any of you guys know what's causing it to idle rough? bad timing maybe?

thanks!

 

If you havent, go ahead and replace the PCV valve (about $5 at any parts place)...that will help alot.

If you havent, go ahead and replace the spark plugs and wires (NGK OEM spec is perfectly fine for normal-compression, N/A engines)

Then start with ignition timing... you can borrow a gun from AutoZone...dont go crazy with too much advance.

Once that's right, now you can work on the idle more accurately. Remember to not plug the eacv back in till the car is off and the Hazard fuse is pulled.

Sea-foam into the vacuum hose and the gas tank is next...it should be getting pretty smooth, and maybe peppier by now.

If you're like me, and want the thing to feel like its not even on, you've got to start looking at replacing the EACV, new grounding wires, and somehow rejuvniating the alternator signal...I'm on a mission!

 

thanks for the awesome reply

i'll try replacing it.. once i figure out where it's located.. lol

well i have new ngk spark plug wires, and i have new spark plugs as well. so yea

maybe it is the timing and the pcv valve.. that's causing to idle rough

just curious

where do u get that seafoam stuff?

 

napa stores have it i hear.

On a '89 Si stock.....it looks like this....http://www.hondaautomotivepart...SI%29 part #6

usually located inbetween the intake manifold runners.......

do a search on here http://www.hondaautomotiveparts.com/home.htm

& and on http://www.acuraautomotiveparts.org/

 

I dont have a good pic, but its VERY easy to find and replace. If you havent done this, then it most likely needs to be done. Sure you can clean it, but it costs about the same as a can of carb-cleaner to get a new one so what the heck...

FIRST, go to the parts store and buy a new PCV. Ask the parts guy to look up the right one for your specific model. Once you have it in your hand, you'll know exactly what you are looking for.


Replacing the PCV:

Warm the car up then turn it off. When the car is warm the rubber grommets and hoses are more pliant making it easier to work with, but that means you'll need to protect your hands from burns when you touch the intake manifold or head...so wear some gloves.

Approach the engine compartment from the driver's side by the hood prop.

Look behind the head, and underneath the injector rail (the smooth black plastic bar with wires). You'll see the PCV device poking up out of the block near the head with the little 90-degree bend pointing back toward the firewall. The 90-degree bung has a hose that connects it to the IM near the throttle body.

I cant remember if theres a metal crimp on the hose or not, but the PCV device itself can be removed by pulling it upwards, and wiggling it a little.

Be sure to install the new PCV with the hose bung facing the same direction, so the hose that connects it to the IM has no kinks.

 

now i know where it is..

thanks for the help guys i appreciate it!


O/T question (i don't want to make another post) lol.. ok here's the question.. i hear sounds like.. a metal inside a can, what seems to be making this noise inside my engine compartment?? loose heatshield?? it's anoyying..

 

Just gotta turn it on, pop the hood and look around.

The first place I would check is the battery and mounting brackets.

If its more of a klang-klang check the metal sheilding over the header, and under the car and along the exhaust.

When does it make this noise? On startup? Whihe idiling? During hard driving?

uhh.. while idiling.. and while driving.. even normal driving it still makes that annoying sound.. i think it's the timing belt.. that's making that sound but im not sure..

o yea, i found the pcv valve, but i can't figure out how to take it out, its stuck! any tips guys/girls?

 

You just gotta get your hand under there and pull upwards...give it a little wiggle, and it will pop out. There's just a rubber grommet that holds it in its hole. It helps if the car is warm, but dont get burned.

i'll try heating it up first.. then trying to pull it out, yea but imma make sure to wear gloves too, just for safety reasons.. thanks for the tip though

o yea, another O/T question.. do i really need to drain the coolant first before changing the thermostat? or can i change it w/o drainning the coolant to make things more easier

 

I dont know if those hoses going into the thermo can be effectively crimped or not. You could let the car get cold, then try to take one off and see if water starts coming out.

 

man, i heated the car up.. and the freaking pcv valve still won't come off..

 

Man, I konw its hard to get ahold of in such a tight spot, will it even twist around a little? If you can get the top hose off, you could maybe get to it with some pliers from above.

man! i tried every plier i have and still won't move, i think the other owner put ******* thread lock.. .. any other option? it won't twist even a little.

 

hey on your can sound. Does it sound like its oming from the dizzy at all? I have a similar sound, but i think mine is the dizzy rotor.

 

Use a second wrench and then put a towel over it. Then hit it with your hand or something. u can use a hammer even...

Any parts store but read before you use this stuff, more threads are popping up about this stuff ruining parts, cats, 02 sensors. I posted not to long ago how to use water to clean the inside of the engine, it works better then seafoam and is safer.

hmmm im not sure, but it's coming from the valve cover, the mechanic said it's the rocker arms, but i dont trust his saying since that was the first time i bought my car to him. but when after starting the car.. there's a oming sound too. i don't know if it's from the dizzy or the starter o wel. i hope it's not the starter since i don't want to spend anymore on horsepowerless high priced parts.. lol

hmm.. i'll try this one, hope it works, but i tried hitting it with a hammer too lol but the sucker doesn't even move.

yea i searched. i saw alot of topics.. alot of bad comments about the product too, so that's why im still thinking about it. (using it or not) o wel

 

Just use water, there are two ways to go about this.

Take your intake off and spray water down the intake manifold, rev the engine if it starts to bog.

Or take the brake booster vacuum hose off and get a cup of water, suck water up and when you engine starts to bog, rev the engine up and take the water away.

o wel, i'll just keep mine the way it is.. i'll try to replace pcv and i'll see what happens

o yea, while the old shitty pcv valve is installed i cleaned the dirt off with some air/throttle cleaner.. and it worked like new haha. but hey i still need to replace it.. so pls help me remove the old stucked one

 

Just do what i did...try it without any luck for about an hour. Then go in the house and drink 6-7 beers. Then go back out there and beat it with a hammer until it breaks . Then clean up all of the broken bits of plastic and insert the new one. Also...PB blaster is your friend
