Engine Problem Shaking

Hi All,

I was driving this morning when my car started to play up. It is a 96 Series II GTS-T, only mods are Zaust and HKS air filter. Basically is slowed down approaching a set of lights, then accelerated as they changed, not hard, very gentle, when the engine seemed to start vibrating or shaking. I could feel it through the peddles and gear knob and it sounded bad. i had to keep driving for a little bit and it slowly got worse. I only drove about 1km.

Any ideas what might be wrong, anyone had a similar problem. My first guess was one of the spark plugs was missing. But I really dont know much about cars.. i am learning though.

Any help would be great.

Cheers,

Ace.

it wouldnt be a miss cos missing doesnt make ur engine shake, check the cam gears for timing. Does it feel like loss of power as well ? if so maybe one of your chambers isnt even working like running 5 instead of 6 cylinders. If i were you id try and get it to a mechanic asap

Check the bolts (four or five) around the fan/fanclutch. I had a similar prob. after a service a little while ago. Turns out they didn't do the bolts up and I nearly lost the fan in the engine bay!!!

Yeah, it wasnt as powerful as it should have been. It didnt feel like i should have driven it either, but i had to keep going, and it kept going.

I'll look at the fan, but i dont think thats the problem.

I left the car where i pulled up so i cant check this stuff out till later tonight. but i am going to get it towed, again, to the mechanic tomorrow and get it sorted out.

I just signed up for RACV, so i'll get them to come out and look at it tomorrow for me. Gotta wait 24 hrs.

I am guessing its not a good idea to drive it to the mechanic.

Cheers again.

How much vibration is there? If its only a little vibration and you have a big exhaust, some times the exhaust can shake the car up a bit. Depends if you have a flexible exhaust connection between the dump and the cat. I know one mine there isn't a flexible connection and the car gently shakes at idle.

If its a hard vibration it could be anything? A fouled plug, a misfiring cylinder anything some thing out of balance....

yes it does. try driving a skyline on 5 cylinders - sounds like the engine is about to fall out until u really rev it (not recommended)

have a quick look over the ignition system

coil packs and spark plugs and make sure theres no loose connections. if you dont know alot of these cars then take it to a mechanic and explain what happened and say u think it might be misfiring on 1-2 cylinders

yeah missing is quite different then having it run on five cylinders man. i have a miss at idle and that does not make my engine shake vigorously, when it starts missing after redline the engine does not shake. IF a cylinder is not working of course it would shake, i shouldve reaphrased my post for less confusion

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.

      Yes they do. For some maybe. But for those used the most by abusers, ie Skylines, the numbers are known. The stock eyebrow height for R32/3 Skylines is about 365/375mm or thereabouts. The minimum such heights are recorded in adjacent columns in the database.

      Hmmm, interesting. Makes me wonder whether there is bias as well. It's the cheapest fuel, so it is used for all kinds of ill-maintained shitboxes which are bound to have issues regardless. Nicer cars tend to require higher octane rated fuel and can't use it anyway. FWIW, the official NSW E10 facts page is decent.
