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

      Slight brake pedal stutter after new pads

      Jack the back of the car up, pull that wheel off, pull that sensor out, and put a bore scope into the hole to inspect the outer casing, see if anything looks damaged before you pull the whole thing apart.

      Ergh... So I pulled the speed sensor out again and the tip was shiny so I think it's rubbing the bearing. The bearing contains the magnets for the speed sensor so I think when the first sensor broke it damaged the magnet ring on the bearing.  This is just a Google image, but there is a hole going to the bearing. So when the tip broke off the old sensor I'm guessing it fouled the bearing... As the magnet is only protected by a plastic cover it would be easy to damage it. So I guess I'm doing a bearing again.

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.

      Steps to DIY sanding car back ready for respray....

      By silviaz · Posted

      Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.

      Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol
