misfiring..

[VL Berlina 5speed]

well this is really peeing me off, car is running like shit!!!
same symptoms as b4, fine till gets to op temp then missfires at 1000 to 1500rpm
ive done all i can to find what is causing it and its not going away

replaced/fixed:
- new dissy cap
- 6 new spark plugs
- new rotory button
- removed the whole dissy unit, checked over it, no orange powder, replaced the 'o' ring with new 1
-fitted a new CAS plug
-replaced temp sensor
-set timing with ear, to best possible
- used timing, gun no beta
-checkd all my high tension leads seam to be fine
-checkd at nite for arcing in any of teh leads or plugs
-new fuel filter

just o2 sensor 2 replace/check, anything else that can cause it? or i missd

Those spark plug leads need to be checked with a multimeter 4 omhs reading.
Also ur not using any coolant are you?

[VL Berlina 5speed]

can you explan the checking of the leads to me plz,
and for coolant 2 weeks ago i lookd at it and it was bout 2 cm below max on the tank, so topped it up with distiled and its gone bak down to 2cm below full,
so ive got my eyes on this as it could mean heads gaskets gone or heads almost there,
but its strange last week it was fine then all a sudden it happens, then it will most likly stop and then happen again




it was fine last night and this morning, then 2day i changed the dissy cap to a new one and new plugs and a new rotoary button, ran fine then left it went out hour later and it was missfiring... so might check over all that tomorrow and then check if did miss something

[VL Berlina 5speed]

just checkd the leads witha muilty meater
and got,
tested it on 2000K ohm setting
lead number........ohms
....1....................002
....2....................004
....3....................004
....4....................004
....5....................004
....6....................004

coil cable.... oo6
would the lead number 1 be causing any major probs or the coil cable

and i checkd teh Afm and its at 251, so might put my old 1 on as that has the cap on the screw punched out then adjust

i also did a check on the ecu and nothing came up besides the usall, air con nutral, speed and start system,
just waiting for the extracors too cool off so i can see if teh O2 sensors clean and fine

any ideas would be very grateful,

[VL Berlina 5speed]

well i think defeat has hit me and money getting givin to some1 is a have to now

try some diffrent leads but nothing,(cheers 4 that clint too)
chuckd my old afm on and just wroser, now it wont runn well at all, sits at 500rpm and misfiring like hell
dam now looks like the suspension money will have to go

The leads reading sounds good but the coil lead being the shortest lead shouldn't have the highest reading!! I think it's still ok though..
The coolant level droping hmm could be a pin hole in the head spraying a tiny amount of coolant in a cylinder causing it to run a bit ruff, but AMf it sounds like.

Ah you put that in while I was writing.lol
anyway try this to check if it's a head prob, with a cool radiator take off the rad cap and put it back on to only the 1st stop where the cap can wobble about but can't come off.
Drive the car like normal and if the miss is gone it's a leak in the head..

i got one more trick up my sleave, because when i took the dissy of to check out the cas it didnt mark it the best and getting it back in was a guess job,
hope that isnt it,

goign to take teh top timing belt cover of 2morrow turn the motor over till its at tdc and see if the timing belt is rught and lined up

then ill try the coolant cap thing,
is there any additive i could add liketeh stop leak blocks to help stop the pin hole leak if there is 1?

I'd try the rad cap 1st as it's the easy...
And if it's a leak u can use chemi-weld..

[VL Berlina 5speed]

and if dosnt turn out 2 b the head could doing that cause some probs 2 teh head?

Shouldn't case any probs but I'd check the cap thing 1st as there won't be any pressure in the rad when u try so it will tell if it's a leak.

well when the enige is hot the pipe is very firm, and when cold its easy to sqeeze, that mean much?

the thing i think causing the water in teh over flow 2 drop back to the same place is that im using distide water so it gets hot and evaporate, then its just left with teh coolant as was b4 and stops at the same level, could this b right?

ok top hose when hot should be rock hard and soft when cold that's because the pressure builds when hot and goes when cold that normal..
And u should be using coolant not distilled water..

i didnt have any coolant, so use some distilled, liek just to top up the overflow bottle, would that evaporate thus goign back down?



note: i havnt fixed the oil sensor prob with the guage not moving, just keeping u informed like u askd :P

no that wouldn't do it.

well once i get the car to acutally run ill try the cap trick

well jsut stopd playing with my car and its still fekd, cant gert it 2 idel fine, adn didnt get to try the readiator trick coz i couldnt get up the drive as it was missing that bad,

was playin with the acc valve, i have a question is it ment to be two peice, like the centre cylinder sensor pull out of the body of the sensor as mine dose???

and the CAS how hard is it to take it appart? dose the whole dizzy have 2 come out, and is it really figgerty? as think of getting a s/h one from teh wreakers and trying that out 2 just see if it is that,

also checkd the ecu for lose wires and brock cables but none vissble, im starting to get vvery thin on ideas
help me

It was fine when cold u said and started to run ruff when it got hot??

[VL Berlina 5speed]

yep, but now its seams to be doing it at cold now 2

if you are going to pull the dizzy out make sure you turn the engine to TDC

yah i learnt the hard way last time it was out, could the dissy being one groove off cause it not being able to be tuned in right?

Yes it could be a groove out, but did u put a timing light on it after..
And if it was out a bit u car would be a slug or it would ping alot...

[VL Berlina 5speed]

yep i had that prob when i took it out
very touchy to get to idle nice, it was a bitch and the timing light was used but it was easyer to tune it by ear,

so do you reackon it could be the dissy off by a groove?
and if u think it is how do i fix it again?
is it :
-take rocker cover off
-turn motor till the inlet valve on first pistion is closed
-then turn motor over till you hit nearst TDC
-then place dissy back in
that right?
