Car doing wierd things !

[MirKz]

Hey all,

well ive just had a 100,000km service done (change timing belt, radiator flush, full service and tune) i dont think this problem has been occuring long (certainly not before i got it done) but today i noticed that in first, after being in a stationary position, taking off sometimes it will semi pop or something.

By this i mean that usually when the foot comes off accel and u let it coast i can often get your standard sort of gurgle/popping.

Well in first when i take off sometimes, and have my foot on the accel, it will actually pop once or a couple of times, maybe its a misfire ?? I lose a lil power for an instant when it does it but yeah.

Dont think its clutch cus

1. just had it replaced

2. it doesnt feel like its slipping, and dont get any extra revs or anything that i can see/hear

Any help as to pointing out what this is ?

My car pops and gurgles on most gear changes if i leave a gap in the change. ie if I change gear slowly

Not too sure if its just that your experiencing. If it is, im no mechanic but its probably nothing.

Possibly gap in your spark plugs are too big? I had that problem and car was running like shit on boost (but you shouldnt be having that problem )

[MirKz]

nar not that problem, thats a familiar sound and know what that one is.

im actually talking about accelorating in 1st gear (unsure of speed) but yeah from a stationary position, it will pop. sometimes once, sometimes a few times, its wierd

[Kaido_RR]

MirkZ, sounds like ur plugs arnt gap right (they would have got changed on major services) when i had my major done i was getting same problem took it back and had the plugs regap to the right gap

[Kaido_RR]

also could be due to u missing the turbo

:jk:

Sounds normal Dan - specially with a new zorst and all - dunno if you've heard mine pop/gurgle - but it's really loud (ie, small flames)

[MirKz]

dude i know what that sounds like LOL, ive had a zorst b4 aswell... but yeah, not tha standard 'popping' everyone gets.

[fane]

can u describe it better then dannnn?

[EVL R33]

Dan,

Is it possible the timing belt was put on a tooth or two out of wack?? Might explain the weird popping you are getting?? (PS I'm no mechanic so could and may well be talking out my ass)

[R33 Impul]

I would think if it is occurring under acceleration then might be a coil pack on the way out. If they are goin to phuck up then it will be just after they have been move (plug change). Spray some CRC or simular on the areas around your coil packs that will stop them arcing on the head and that should stop the misfire.

[damono]

or... take it back to where you got the service/work done and let them fix it. Thats if it was working fine before you went in. They probably would be able to tell you what it is straight away.. after all it is what they do for a living

Brett,

Timing belt off by one tooth - ouch - don't say that! I can hear poor daniels wallet opening WAY too wide

I've never heard an N/A misfire like that before hey... on acceleration i mean :| But in a turbo it's usually coil packs or base timing well-retarded, or just plug gaps!

[MirKz]

okay, took it back today, apparently some of the coil packs are arcing a little or something,

but apparently on the computer diagnostics its fine. might just sit on it and hope it goes away LOL i dont wanna fork out for new coil paccks

Mirkz try this.....It works.

[MirKz]

yeah but that means ripping apart the intake system etc to get under it to open up where the coil packs are... its hard!!

so dont actually spray the coil packs themselves? just the surrounding ? or jus spray everything ?

[R33 Impul]

Yeah, bascially the area around the coils packs , doesn't matter if you get some on them though but from memory you should be able to lift the cover up enough to spray without taking the cross pipe off.

[ix9]

mmmm, CRC cures misfire eh.......

[RB20LagWagon]

if coils are arcing out against the head, then it could be that the rubber surrounding them is cracked, aparently the cure is to tape them up so the spark cant get thru to the block its usually due to the rubber deterioating etc etc

[MirKz]

cheers guys

KYM WE NEED A WORKSHOP SESSION SO WE CAN FIX ALL OUR BUNG CARS.... and MAYBE.....gut my cat LOL!

[R33 Impul]

It does work, had the same problem with my 2 door a few years ago and the guys from Myaree Dyno Tune told me as a temp measure to do it generally last about a 3 to 4 weeks but hey beats misfiring.
