Could be spark plugs.
 
Re: Vibration caused by low rpm idle..Engine seem choked...

could be misfiring of spark plugs. experienced that when i change mine to after-market ones. me same ride as yours, a humble 520. send to wrkshop for a quick check.

Just serviced by PML last mth (as still under warranty).
1st service @ 25k never change plugs right?

Friend told me that could be fuel pump going to fail as he had that
problem before. Dunno leh...

Yup. When I took out my plugs at 40k to change them to the Volker plugs, one of them was already corroded. And can you imagine I was told by PML that they're supposed to last till Inspection 2?WTF?

wear & tear of fuel pump are not that common thou, let alone if miledge is not high. 25k on the clock can change plugs liow! if you're talking abt stock plugs, no need even to re-gap them. don't dunno leh anymore, drive down to any of the listed workshop for a quick check, kau dim!

Incidentally, Even tho only 22k, my rear tyres already botak

Bro, at 22,000km, I dun think it shd be the fuel pump at all. If spark plugs is indeed the cause (a mechanic can verify easily), now is yur chance to switch to Volker plugs. Do a search and read forummers' feedback.

The fact that the rear of your tires are botak and if u are not the first owner cld be because the previous owner does alot of hard driving drifting etc hehe or he passed on the good tyres to someone else before selling the car to u.
 
Re: Vibration caused by low rpm idle..Engine seem choked...

got rotate tyres or not? btw may check the inigtion coil too.

errr..don't think previous owner did any hard driving leh cos I bought car from a
rich 50+ year old auntie...
When I viewed car, she got Pocohontas stickers all over the windows & instruments
until cannot even see speedo
 
Re: Vibration caused by low rpm idle..Engine seem choked...

it could be sparks, ignition coil or engine mounting....

i had my pistons msifiring, sparks corroded.... ignition coil broken and engine mounting worn out when my ride was vibrating at low rpm 1000 esp worse with a/c turned off.....

BVO replaced my coils, sparks and engine mounting and now ride is idling at 600rpm and feels like lexus :)
 
Re: Vibration caused by low rpm idle..Engine seem choked...

Ya... I had the same vibration problem with my 2002 E46 as well. Went to BVO, 1 hour job to get the engine mounting replaced and wa la... could not even feel the engine idling after that.. in fact for the next couple of days after i did the change, sometimes when I stop at traffic light junctions.. I even had to check my rpm just to be sure that my engine is still running... :)
 
Re: Vibration caused by low rpm idle..Engine seem choked...

On my ancient 318 - the vibration at low rpm was caused by a broken breather hose - engine nearly dies due to lack of air and vibrates like hell....replaced rubber hose and all was ok.

hi, so how much does it cost for the replacement of ur engine mounting??
 
Re: Vibration caused by low rpm idle..Engine seem choked...

Try the air filter, mine is having the same problem, leaking air ....!
 
Re: Vibration caused by low rpm idle..Engine seem choked...

Sent to PML as under warranty.
They changed the ignition coil which they claim crapped out.
Good as new now...FOC too
Thanks for all the responses

Re: Vibration caused by low rpm idle..Engine seem choked...

The engine mounting for both sides - $140. I did some other stuff as well, so the labour for the engine mounting portion I estimate about $50-60. Total about 200 bucks plus minus... :)
