Only when I am maintaining speed. If I slow down or speed up it smoothes out. I had the axle inspected. I replaced the EGR valve. I even put a K&N air induction kit in the thing incase it was an air/fuel mixture issue. The kit made no difference, besides an increase in power. There are no particles in the engine oil and a tune up made no difference either. It started when I drove above 90 mph down the highway. Any ideas?

 

do you have enough oil, i know you said you looked at it but did you check the level

 

how do you know vtec is causing the problem?

at constant speed (and in the proper gear, therefore moderate throttle) vtec should not be engaged.

generally it'll only come on while you are accelerating and the rpm's are above 2.5k (or so).

(unless it's different for you car, mine is a 99 I4 sohc)

 

I did check the oil. In fact I have changed the oil twice since the symptom appeared last summer. I use only synthetic oil. Also, the roughness occurs in every gear.

I don't know that the engine is the problem, which is why I had the axle inspected and the EGR replced. It could be the rings/cylinder walls I guess, but I intend to troubleshoot peripherals before tearing my engine apart.

I plan to replace my catalytic convert next. If it isn't the problem, at least it should increase performance. Next I'll replace my mass air sensor and my O2 sensor. If that doesn't work, then I guess I'll have to rebuilt the engine. Any thoughts?

i think it your transmission since you said the "roughness occurs in every gear"

have you check the transmission fluid lvl? if so

8stick* = engine oil

automatic* = go to the dealer and get the fluid from them.


*maybe i might be wrong whos know try.*

you don't just use engine oil in a 5 spd bud. you use honda MTF or the equvilant

 

have you tried this yet?

i think you should call up Honda and tell them they printed the factory service manuals wrong, because it says you can use 5w30 in it just fine

 

<U>Here is the skinny about the MTF</U>;
Honda used 10w30/5w30 in the 5spd UNTIL they came out with their own special blend of "herbs and spices".
They named it "Genuine Honda MTF"
So you guys are both sort of correct

well duh, it a honda dealer they sure will give you MTF or you can put in regular engine oil. check your car manual it said that you could use regular oil too. =} your just ignorant trying to correct me. when you know what i mean.
it does say after putting engine oil in it, only for awhile till you have to get it flush and get fresh fluid. that what i remember when i had my accord manual. which now i dont and dont feel like going out to the car to see what my cl manual say.

 

uh. why bother wasting the oil tard.

 

why bother wasting gas and money...... and beside your going to need a flush anyways

 

oh yeah now your making a TON of sense. yup, your going to need flush it after like 60k instead of like 200 miles you retard. get off the forum, your not cool, and you don't help.

it make sense to me... as the manual said you CAN use engine oil. why would you add mtf to the car when you need to flush that my question. there is nothing wrong with adding engine oil to the trans and why drive it for 60k when you should flush it when you have time? dude you really dont know anything. how aint i helping your the one that saying i cant use engine oil in the trans wtf? i dont see you helping beside giving out information to people that would burn their pocket. not much but still. if you dont like what i said dont quote me simple as that and for starting this arguement like i said your just ignorant

like it was said before, you can use it, but its not recommended. but hey, its your car. expletive it up how you want. im seriously done with your retarded comments. you don't know anything, you obviously don't know how to maintain a car.

it not recommended that why you ONLY used it till you have TIME for a FLUSH. you obviously cant read? like i said man your ignorant for the 100x hahahah i just laughing at you how your mad and trying to arguing it up with me HAHAHA maintain a car wtf? so your saying put in mtf and drive for another 60k+?? that dumb... i would put in engine oil and drive till i have time flush it simple. why engine oil? i aint going to drive 20 minute from my house just to buy mtf expletive that and 20 back. wasting gas and money on somthing i can go to auto zone around the corner and pick some up. so YOU dont know anything about maintaining a car.

 

riiiiight. so i'd waste time pouring oil into my transmission, then flushing all of it back out for no reason when i could just put oem mtf fluid in it and not have to worry for 60k. smart idea

 

the main thing is just useing some sort of oil so you don't fry your trans. yes I agree that the honda mtf is probly better for the trans, but regular oil works.
and back to the topic, it doesn't sound like a problem with the vtec. have you checked the balance of your tires, or alingment? even a bad wheel bearing, or warped rotor could cause probs. now if it hapenes in every gear at a certian rpm, then yeah I would look in to internal trans, after checking clutch.

what the hell you talking about? either way you still have to poor it in. you cant just buy mtf and push it in, close the hood. i rather waste my time then money. for no reason? there is a reason that why u would flush it out.. okie if you say there no reason why add mtf and flush at 60k tell me that.

 

wtf did you just say.

if i were going to change my fluid, i'd drain it and fill it with MTF not oil. not to mention you don't even know the right velsicoity of oil to use. so just shut up and stop trying to fight me on everything.

that what i told him about the transmission and the topic starter if has a stick he should look at the transmission lvl and if it need to be added with fluid. i said he could use engine oil too but sony think he know it all and said no he should use mft. which i think if you have low fluid in the trans you should just put engine oil to it and flush it when you have time. it already giving you a sign of somthing is wrong.

hey man the only reason i didnt say what type of engine oil to use because i dont remember and like previous people had said 5/30 and 10/30 and i was talking about adding it then flushing it and adding it with MTF. your just counfusing yourself. go to sleep. it okie to be ignorant but when you know that you lose just give up. and you say i start a fight with you in everything? excused me sir but your the one that quoted me. thx =] point given. to bad for you
