Car Lightly Vibrates Like Stalling When Stationary

[R33Turbo]

hey,

Everytime in the morning when i jump in my car to warm the engine up i realise there are ocassional slight vibrations from the car...Its light vibration but definitely noticable, its kind of like when about to stall vibration but obviously not as bad but it occurs not only in the morning but even after the cars warmed up. However, I don't realise it at the traffic stops.

Any idea guys? Is the engine bad or something? Time for oil change u reckon? or 100k service (even though it shows cars done 50k, i don't believe).

Cheers

Come on guys, no one had problems like this before? I've tried to search for similar topics but couldn't come across any cuz others are actually stalling, and will vibrating whilst accelerating etc.

However, my car doesn't stall or vibrate as bad to stall when at idle and it goes away when driving...BUT it does vibrate VERY BAD going up hill at slowly but with abit of correction with acceleration the vibration goes away (i thought it was the clutch but now i think its connected)

Sounds like your spark is breaking down.

Could be plugs, a bad coil pack(s) or

ignition module (R31 > R33 S1)

Id start by replacing plugs, if it continues check the coils for arcing etc. Wrap them in amalganising (spelling) tape.

If that does not help chances are its your 15 year old coil packs letting go.

Theres a few options:

1. Splitfires (good alternative -not as good as new stockies IMHO)

2. Stockies (New) $$$$$$

3. Another after market solution (bosch, msd, AU falcon etc)

Yeah thanx for your input Wheezy, ive assumed it was the plugs and changed them to irridiums today which have SOLVED all the vibration and shudders whilst going up hill. The platinum ones were on the way to go...

And many thanks to the members who have given alot of attention with huge amount of reply advices

lol sarcasm?

haha good issue though cuz i was having the same problem only i did what you did and presto!

i changed to splitfires + iridiums and it was gone.... maybe i should have just changed the sparkies lol but the SPLITs are awesome.

[H@ME]

either that or atmo's bov not tight enough?

Yeah sparks in a untuned car will cause this.. Iridiums regapped from 1.1 to 0.8 I would assume you had. Its actually missfire thats happenin at idle I hate it but live with it.

What can you do I'm not going to bother paying for stupid platniums until next time.

[nuffsaid]

Yeah I remember hearing from many people that it is misfire as well.

Typically from coil packs that are nearing the end of their life? or maybe a gap that is not small enough?

wat is the the difference between 1.1 and 0.8? i just bought mine and were apparently 2 degrees cooler than normal and put them and it was working fine? what do they come as straight out of the packet? i think we measured it.. lol cant remember how much it was.
