I need your help

I have 2002 RSX Type-S. I bought it about 1 year ago. On 700-1000 RPM-s Engine has vibration and nobody could in my country repair it.

I attempt to correcting this problem by this steps:
1. We measure pressure in cylinders, but they are equal 11.
2. I changed spark plugs with bosh platinum, but noting changed in this problem
3. We inspect all engine mounts, but they are in excellent condition and there is "Ingalls Engine torque Damper" too
4. Computer testify done well, all things are working without problem

what do you think about it?

P.S. maybe there is alike this thread but I can't find it
Because my English is very poor I am writing this post by dictionary :D
P.P.S. I live in Georgia, not US state, it's country near Russia

Ingalls Engine torque Damper remove that and see if it goes away.

I tried removing ingalls but there wasn't difference

also we cleaned injectors and throttle

just a vibration in idle? could you explain the vibration in more detail? what mods do you have done to the motor?

Type-Spaz

Put good spark plugs back in


as far as the vibration is it literally only at that rpm? So not at idle but just a little higher? Check your axles and make sure they are good. I've had a crazy experience with vibrations with a bad axle.

nahonda04

really, ive never even heard of k20 axles going bad lol unless under heavily modded k20's

Old spark plugs needed change, they was yellow
Do you think bosh sparks are bad? Maybe You are right, I think change they with NGK spark plugs

I have problem with idle rpm-s and also when I start drive with low RPM-s, from about 1500 rpm everything is good.

I don't understand, what kind of AXLEs? Drive axles?? Are you sure? Maybe you speak about another axles?

I changed only exhaust header and down pipe But i think first owner changed more things

because:
1. When it comes in Georgia from USA exhaust header and down pipe was not mounted with each other. I think first owner has changed racing exhaust on stock before sell car and forget mount them.
2. How I think there was Cold Air Intake System, because stock wiper reservoir was not mounted well, it was quickly changed from CAI kit slim reservoir. Also there was poor mounted stock air filter box and it had not air guide.
3. There was not any audio, not speakers, I think first owner had good audio system and removed it.
4. It had not front bumper lip. not stock, not another one.
For other words... my RSX was tuned and then untuned for sale :D
Maybe on my engine is tuned Skunk2 camshafts? I don't know...
Perhaps another things is changed....

It's my RSX-S maybe anyone knows who is first owner? It come from New York


And I forget write in firs post: my RSX-S needs 18 mpg in city with soft drive, is it normal?

I didn't say the old ones didn't need to be changed... but bosch spark plugs are junk. Especially when you are comparing Iridium spark plugs (OE) to crappy single platinum cheap bosch plugs you put in.

Type-Spaz

As far as axles we only have one set of axles lol CV Axles or CV Halfshafts... whichever you want to call them.

I use to have a 96 Honda Accord with what we called the "earth quake gear" In 3rd gear only from 2000-3000rpms the car would shake like a god damn earthquake. But ONLY in that gear and only in that RPM. Craziest thing ever. Took me forever to figure it out. Turned out to be a bad axle. . . I've seen axles cause slight vibration to severe vibration and at different RPMs, Gears, or through out the whole range.

This is just an idea I'm throwing you to check out

to OP, how do you have a header and a down pipe, is the car turbo'd or no? do you have kpro? can you feel it thru the floor board?

turboteg2nv

If it's only vibrating at idle, the CV halfshafts wouldn't be the culprit because there's no load on them so they shouldn't be spinning at all to cause any vibrations.

They are not cheap about 50$ for 4 piece same as NGK laser iridiums
but in my country I could not find NGK IFR7G-11KS and I bought Boshs because they fits on my engine. Because I prefer fited bosh spark plugs
I know NGK is better and I decide buy NGK IFR7G-11KS from USA

I have vibrations also in idle and because I didn't understand about axles


I have vibration on idle and when I start drive from lower RPMs

In my opinion maybe there is some disbalances in clutch sistem? pressure plate?

I haven't Kpro and turbo
I feel big vibrations from steering wheel, also dashboard and panels have little chatter.
maybe there is some bit little vibrations from floor, but I don't remember

P.S. Maybe I don't answer right on some tings on your posts and maybe some my posts aren't clear. Pardon it's all my English knowledge :D

I had a really bad one that caused crazy vibration but during 2,500-3,500rpms.

I swore it was alignment or tire balance. Changed the axle, perfect. But doesn't sound like the problem here.

You sure you don't have aftermarket motor mounts? (Avid, Hasport, Innovative)

VTEC79

I don't know
I'll see they tomorrow, but I don't know can I or not see diference
In this moment there is 12:30AM

I know this is an old thread, but I've had a similar issue with my Accord after the engine was rebuilt. Please watch the video and tell me what you think. The car had no vibration pre-engine rebuild. It has epic interior resonance vibrations at about 2000 rpms. What should I be checking for?

Many thanks!!!
