Hi chaps,
I managed to take out my spark plugs today, there was only one plug with a tiny trace of oil on it, nothing too heavy at all. Placed a new set of plugs in, took it down the road and it was exactly the same, lack of power and a misfire at mid revs that cuts all power (like traction kicking in) :(
Can anybody recomend a place that sells dis packs and leads other than vx (or is it main dealer only part) and is there anyway of testing a dis pack off the car?
Thanks once again

have you read the fault codes? check out how to paperclip your car.
it could be the crank sensor / cam sensor.
Does sound like DIS pack though.... you can test them (but i don't know how) someone who does will be along in a bit.
As for replacement ones.... I do know of one in a local scappy. Its a 1995 3.0 Elite with the DIS still on it.
What kind of prices have you been quoted so far?

Hi, my car has not shown its managment light through this problem so have not checked codes. I think I will go and do it now anyway because there is no harm in checking... It may shed some light on it... ;D
As for a second hand dis pack im not so sure (unless there stupid money!) as I think im correct in saying there are a pig to change so only fancy doing it once! ;) but thanks for the offer
Thanks for your advice
-
Thanks VXL V6 :y
-
<<<<<UPDATE>>>>>
I just carryed out the paperclip test even though the light wasnt on....
12 Normal start
19 RPM signal (crankshaft sensor) Incorrect signal
16 Knock sensor 1 No change in voltage
Is it possible that both sensors are playing, any ideas! :'(
-
Code 19- you need to do the test on a V6 with engine running.
If code 19 is still present then you will need a new crank sensor definately.
-
ok... be right back... sorry neighbours ! lol
-
ok, just did the same test with the car running, in park, handbrake off..... and got the same results. 12, 19, 16
-
Change the crank sensor without delay!
-
19 WILL let you down, so plan changing that one asap.
However, the knock sensor will make it run like a sack of sh.... above about 2k. not sure why it not bringing eml on though...
-
Super, thanks very much. I should put the local vx number as friends and family! ;D
Will the codes need clearing or will the fitting of a new sensor clear it?
Thanks very much

-
You can have them cleared but they should auto clear after about 10-12 starts without fault. IIRC.
-
have to agree with others, get that crank sensor changed... and have it done by the weekend, if not sooner.
Report back once its changed, let us know if you still have the problems :y
-
The knock sensor will likely be damaged wiring, rather than sensor, and hence can be repaired :y

Why at the same time tho??? would it not be misreading because the crank sensor is broken? where is the knock sensor located??
-
There are two knock sensors, one for each bank, and are bolted to each side of the block midway along.
Sensor 1 should be associated with bank 1 (1,3,5) so will be the drivers side. The wire comes up from behind the alternator, around the aux belt tensioner and plugs in at the cable tray. Check that it is free and not trapped all the way from the connector to the sensor and check for damage to the cable outer. It is a screened cable so shorts out if squashed or trapped.
Do check that your EML comes on with ignition and goes out independently of the oil light....the bulb may be blown or missing, or someone may have wired the EML to the oil light to hide a problem.
If the EML is not lit then there are no faults at present (ie right now), there may be codes stored but these will be from faults that were intermittant (in the past).
The 19 tells us that your crank sensor signal is degrading but hasnt actually failed yet so unless you want to get stuck...change it.
If the EML is not coming on during the 'misfire' then I would go for the DIS. Yours should be the early type and E-bay is OK but buy new.
-
Is there a resistance check I can do on the crank sensor or would it only read from a osilsiscope (waveform)??
Bit confused now, looks like I am going to spend the week collecting parts and fitting them all on saturday! ::)
-
Just removed my dis pack.... on the reverse side there is some corosion in between two of the blocks, on a small wire strip.... is this the same corosion you guys talk about?
Is there anyway of posting photos? may be better to show than discribed. ::)

sorry about the size! ::)
-
Just went to remove the crank sensor and its has been replaced at some point before, the wiring has been relocated as per the tech guide on fitting a new one..... and as my EML was not on or has not been on im guessing the fact that a new sensor is on there may mean that my cranks sensor code may be an old one.... :-/
my head hurts :-[
-
Best thing to do is get the codes cleared and see what comes back.
If you put your location in your profile then there may be someone close by who can reset them for you.
-
UPDATE>>>>>
I decided to go for a dis pack as my engine check light was not on and the crank sensor has been replace in the past (spotted the new wire location). I fitted it on Saturday.... put it back together and went for a road test.
:( no different
Went back to VX today they had a crank sensor in stock. Just fitted it, went on the same road test but was back in half the time
8-) at last I can start driving it again!
Thanks once again for everyone’s help, moral of the story, keep a paper clip in your glove box and check for codes regularly and don’t wait for the light to stay on....
:y

Glad to hear you got it all sorted matey ;)
