Are they really so ruff?

[VL Berlina 5speed]

was sat in a vr 5speed ute at work today at idle with no radio on just the engine and the sound off the car idling,

i felt the whole car vibrate while i was sat at idle and thought geez this is ruff, it didnt sound to have any missifirng just made the car rocked a bit.

ive her the buick is a bit ruff and shakey but didnt know if it was really that bad, how do yous tend to put up with this? or do you grow aquatent to it over time?

im not here to braging or bash either motor or to choose a fight but just it stood out to me like a dogs dicks as im use to the rb30 which is supposbly quite and smooth

[VLDavo]

this was like in my mates vr it rocked and stuff...... it actualy had injector problems and had abit of a flat spot ....

[J_D]

I actually like the roughness of the engine. Mine is probably even rougher than standard as mine has VR computer and injectors. The car shakes around at idle but its smooth as on the highway and when you put the boot in.

[88GreenVN]

The harshness is from crook engine mounts.

[SweetWagon]

The rough idle has always been a problem in the buick v6's, over the years they did use the bellmouth in the intake manifold and experiment with different tunes etc which helped on idle, it was pretty good but still not perfect. Personally i dont mind it, you get used to it after a while. More of a feature than a fault

[J_D]

Yeah its good to know that there is actually an engine in there. I dont understand why there is this big thing about NVH. Its a car, its powered by explosions, get over it. Making a car quiet just disconnects you from the driving experience IMO.

VR injectors are exactly the same as the VN/VP injectors. There is NO difference.

VR's are the smoothest of the buicks. VN S2/VP second smoothest and the rough one is the Series 1 VN.

[nathans1987]

i had a s1 manual and it wasnt that bad, there was a mild harshness but nothing you would notice unless you looked for it.

[Morton]

I've got a VP series 1... fairly smooth cars. Took out the bellmouth, installed a VN computer chip, and now she idles like she hates me. I absolutely love it. ^^

[PaRaDoX]

vn s1 had a lumpier cam stock :P, they're harsh and i love it...

[STEALTHY™]

I just got a Series 1 VP, and yeah its a bit rough. But i still havn't given it a thorough go over.

That and the fact as soon as the money is saved, it'll get a 5 litre and a 5 speed.

[38VNIT]

i own a s1 vn and i dont have that problem, it is a little rough but no different to mates vl's, vz's, vt's, vk's, but then again we are all people or care for our cars and keep them in good order, thats and i drive random cars regularly so ic prolly grown acustom to the roughness...to me its more noise...

[dirk]

its a tractor, accept it. Mine seems fine until I drive the wifes quad cam diamante where you cant hear or feel the motor at any speed including idle. its so smooth its plastic and anemic; dam things fast though.

[JD]

it really depends on the car, i have been in some that are smooth as silk and some that are rough as guts

[padrickz88]

yeah it depends on the car and how its been treated. my car is pretty smooth actually except for when under load (in drive and stopping at the lights or something).... besides that its usually pretty smooth really and if i leave it started and take around 2-3 steps i cant hear it.... only thing i can hear is the original "lifters tick" but thats a vn thing but the actual engine i cant hear... if that makes sense *rolls eyes*

yeh my vnv6 was smooth but have been in smoother vn's b4, others ive been in have been rough as

[Full Spectrum]

Slap a Buick V6 into a VE and the car itself will make the engine quite that's modern cars.

Mine is fine when driving, It's more slightly a miss when idle in park then in drive. Doesn't shake the car around at all.

[crazyspoon05]

Mines pretty rough on idle but smooth under acceleration so no complaints for mine, really love being back full-time in a Commodore after a few years in the 'wilderness'

[JD]

yeh my vnv6 was smooth but have been in smoother vn's b4, others ive been in have been rough as

yeah yours was hell smooth and tonys was hell rough

[I LIKE COMMODORES]

I've had a few vn's in my time (s1 & s2 autos & manual's) & in mech good order they dont have a problem beeng roughness, Most of the guys up there ^^^ know what you mean & i know too as i have dh mates lol, But another suggestion is...He has a spark lead off which does cause viberations & roughness. (Trying the be cheap & makeing the engine sound lumpy with stock cam)

[PaRaDoX]

i changed my engine mounts recently, its REALLY smooth now

[andyman]

my vs is pretty good, my uncle thats been a mechanic for years commented on how smooth it was for a ecotec but its runny pretty crappy cause of my oxy sensors and injectors

the ol buicks were not a very well balanced engine to start with

[Full Spectrum]

Hey wrong place to insult the buicks lol

[-UNKNOWN-]

I just changed the engine mounts in my VR. Still seems "lumpy"

[VNCalais98K]

I thought my idle was rough till i pulled up next to a worked v8 of some sort (valiant/mustang style). lumpy cams straight through exhaust...

It was so loud that my car was shaking and his panels were all visibly vibrating...

Was insane... i did my window up so i didnt get blasted as he took off...

Had heavy clutch too.. it would wait for traffic to pull away, lurch forward, stop etc...
