When driving its like a 'stutter'
it jolts foward and back and when sitting at lights or on the spot the revs drop to 300 - 400 and just wants 2 die if u put ur foot on the accelerator it makes it sound like a WRX backfiring pop pop pop i really need some help cos i need my car bad cant get 2 work without my car

it isn't overheating tho the temp is normal and how it shud b which is lucky
try n help me out guys thanks in advance

mechanics should find the fault, but if it hasn't been checked , have the cas [ crank angle sensor ] checked as it can cause major firing problems which include the symptoms you decribe, took me and the mechanic nearly 4 months to find my problem, changed the cas and no more problems and more power.

[STYALR]

im not sure if they have checked the CAS but they r staying there 2nite to try and get it done
what sort of things does the CAS do to your car when it is screwing up or dying on u? can somene list them thanks

-runs weak
-misfiring
-wont start or will and run very crap at idel
-misfiring when gets to operation temp

if you have a spare dizzy (the whole thing) take it to the machanics and get them to swap it and see if that sloves it, check all your leads for arcing and shorts and the dizzy cap for cracks and dirty points

[STYALR]

VL Berlina 5speed ok i will give that a go hOpefully solves the prob let u knw how it goes

the crank angle sensor provides the ECCS [car computer] with two different types of data signals --- 1] reads engine speed & 2] crankshaft angle or the position of the piston. within the sensor you have 2 LEDS [ light emitting diodes] , 1 LED reads the speed and the other reads crank angle, when the bearing in the distributor goes , there is a fine red coloured powder/dust released which in turn fouls these LEDS so that it can not read properly thus you end up with a series of problems with engine firing, as even the ECCS [car computer] has difficulty keeping track as it is bombarded with signals that do not compute. cheers

anything yet???

I have had the same problem with my VN commodore, i took it for a drive last night until the engine was at operating temp, then pored water of the crank angle sensor to cool it down a bit. Cooling the CAS seemed to help considerably.

[STYALR]

OMG just got my car back from mechanics everything was fine they fixed sum leaks in my pipings n stuff then when car got to normal operating temp after driving around for say 10mins the misfire and low idle kicked in i wasted so much money and time at the mechanics its not funny

I am convinced the mechanics i took it 2 r slow, i don't even think they checked the CAS/dizzy i asked him 2 check dizzy and CAS he rekons it wudn't have been that.

Im asking anyone who can help me out i will pay U instead of paying a stoopid mechanic who took me 4 a ride i rekon. If ur in Melbourne willing 2 check my CAS or dizzy and determine if they r faulty or not let me knw im desperate now
thanks guys

[VL Berlina 5speed]

did u take them a dizzy to swap? or were they just nobs and wouldnt even touch the dizzy?
i seariously think it is the cas as mine was doing that, ran fine then got to normal temp then startd missfiing

[STYALR]

Nope i didn't take them a dizzy and yes they were 2 lazy lol meant 2 b professionals and there 2 lazy 2 check assholes i rekon. How much for a dizzy & cas if i need a new one?

cas price depends on where you get it , ranges from 80.00 $ up, you can put it in yourself if you are mechanially inclined or auto electrician would do it for approx $130.00, secondhand dissy approx $ 75.00 up. cheers

My friends VL has the exzact same problem. It takes several minuets to start & is vitually un-drivable because of the misfiring. And the car is also for sale so it has to be fixed before it can sell.

[ucwepn]

Take it to a shop that knows about vl's, I took mine to Selectmaz and there is a bloke there who is a VL expert, the shops in epping. Or bresciani or rajab or JPC, they are all in the northern suburbs and will fix your prob.

[TOBSTA]

my 180sx had a ****ed coilpack... exactly the same problems you have listed

Sounds like what happened to me exactly, changed half the bloody car paid them $900 had to take it back 10 times every time they reckon they fixed it but after a couple of days problem would return, I have now a new ECU, a new internal pump, new pressure reg, new 2nd hand dizzy, new fuel filter, new coolant temp sensor, they even tried swapping the coil. I told them at the start Its gotta be the airflow meter or the CAS, But they never agree that it could be something because they always try and screw ya around. I'm pissed of mega with ULTRATUNE EPPING VIC, people please don't ever go there and don't even let your worst enemy go there.

I will be taking mine to bresciani when I can afford it, I'm sure they have an understanding about VL's.

I know how ya feel mate. Mine is overfuelling for some reason. I still think its the AFM playing up. And my problem comes and goes all the time so its very hard to diagnose, Although I'm suspecting ultratune couldn't diagnose their a$$ from their elbow.

[adrian222]

yeah mine had the problem of needing a new dizzy, then my coil screwwed up. so i replaced all them. ur mechanic is SHIT thats the first thing they should of looked at.

[yobbo88]

my vh had the same misfire that you describe (wrx sound). i had one dodgy spark plug in... i bought 3 new sets of 6 and got a dodgy one everytime! took it to an auto electrician and for 40 bucks he did his little tests and pointed out the dodgy plug. it didnt look damaged so the mechanics may not have noticed. look into it i spent a fair bit doin a bunch of work and then $4.50 later my car was running better than it had since i bought it with one little plug

[warney]

wanna have a idea mone was doing the same , but not as severe retard ya timing a bit and then try the internal fuel pump.....is the external one making noises ???

[warney]

the auto elect said that cas either work or they dont work its as simple as that as well ,there is no inbetween !!!


if ya in brissy and you have this problem let me know coz i can give yuo a number of a fella thats fantastic

[grasshopper]

Also, you might want to check that one of the wires from the harness to an injector isn't broken? I had same problem with my VN. A new fuel pump solved it temporarily but it came back 2 weeks later. Mechanic tested the power to the injector wires and one only had power intermittently. When he checked it, the wire was snapped inside. He repaired it and the problem went away. If the wire is ok, the coil pack and plugs might need replacing if you haven't already done so. After doing all of the above, I haven't had any further problems. Hope this helps.

80.00 for a c a s , thats cheap , i got 1 @ trade for 92.00 but it wasnt silverline , if they make them!!!!

check the rotorcap crackes centre brush/spring

[Stewart1000]

here's what you want to do, remove all the leads, take the cap off the dizzy (distributor), thing with the spark plug leads coming off it, a screw on the top, and one on the bottom, that comes off easy.

im talking left and right if you were on the passenger side of the car looking and the dizzy.

to the right hand side of the dizzy, hanging off the side of it it a bracket with a bolt through it. You will need to remove that bolt to get the dizzy out but first mark the position in the bracket where the bolt it sitting so it can go back there later.

now under where the cap sat you will see the rotor button, find a way to mark what position the button is in, where it is pointing to, THIS IS IMPORTANT.
It needs to go into the same position later.

remove that bolt in the bracket and pull the dizzy out.

find a mate who has a working vl or r31 skyline and do the same to theirs and swap them around and see if your car runs, also check if theirs runs.
