Just recently I got my car serviced and every now n then when i'm idling at lights... the car suddenly shakes and feels like it drops. It's very slight but noticeable... don't know if i'm just being paranoid, but does anyone know why that happens? Is it coz of new oil?

Another problem I sometimes get is when im doing say 30km/h and want to crawl a bit faster and SLIGHTLY press down on the accelerator and hold it, i get a fluttering sound like "pht ft pht ft..." then when i press down a bit more the normal engine sound kicks in and it goes just fine...

i :yes: someone reassure me!

Thanks

i think i'm having this same problem. only started recently,

On idle there is a faint shudder, can be heard through the exhaust lightly as well, car has also started to backfire just a little which might be related.

ahh race_snooze u gave me an idea. u say afm... i have a pod filter installed with no heat shield or support (its just like... hanging there), i wonder if that could be it.

...unlikely...

i reckon its the coil packs, it seems that if the coil pack/packs are bad there will be a loss of fire to one or more cylinders, which could cause drag on the engine and cause that "shudder" I sometimes get. apparently it can shut down some engines completely :S.

T187 do me a favour and get your coil packs checked, then tell me if that's the problem lol i'm a bit strapped for cash atm,

is it just me or do camry's and accord's not get these kinda problems?

lol

Im a bit strapped for time!

my cars pissing me off lately, first it was missfiring, turned the boost down a touch and all was good but still was not totally gone, so next step was coilpacks, went out and bought a new set, then the problem dissapeared for about 2 months, so i still have them rapped up in the box, then a couple weeks ago i noticed the slight shudder so im not sure what it is, planning on changing the fuel filter, undoing,redoing my piping, and seeing how that goes, replacing the coilpacks(however i checked the plugs and packs after i had the misifre and they were fine, no hairline cracks)

i'll post up when im done with all this work, now to find some time!

you could always swap for a charade, 3 cylinders FTW!

just an update, i got round to sorting out my car today, did a compression test(all good), went to change the plugs but nobody suppplies them here, they're NGK r7119-8, might have to get diff ones as these are pretty expensive and hard to find.

so bolted the old ones back in, (before i did i carefully cleaned/sanded the ends down as they were pretty dirty and built up), had new splitfire coils but decided i would put them in when i change the plugs, so all i ended up doing really was cleaning the plugs, Problem gone!

no more hesitation that i can notice and also my missfire at 3500-redline is totally gone! for now anyways

      I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!

      Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.

      The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!

      The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
