My car has developed what feels like a misfire. Its gone from being silky smooth to being quite shaky, especially under load. On tickover the rev needle flucutates.
I did a paperclip test and produced 12 and 19 (Incorrect RPM).
Does this code point me in a particular direction or is it just a matter of checking plugs, leads, fuel filter etc?
Thanks in advance for any help.

Failing crank sensor, needs changing asap
-
The crank sensor fits into the block near the oil filter canister. Held on by an easy to remove small bolt Torx 8 or similar. The sensor then just pulls out of the block.
The key thing is to route the wiring carefully away from oil and heat when you install the new one.
If you are lucky it will have the part number on the head of the sensor(oil filter end) If you are unlucky it will say "SAAB" like mine!
-
Is that all it can be?
The crank sensor is less than a year old (genuine Vauxhall Part) and has been re-routed as suggested in the maintenance guide.
-
Had the same fault/symptons on mine recently fella with code 19. Took the advice of the guys on the forum and bought a new one with the TC card (good discount) :y. Re-routed and runs like a dream now.
-
A 19 is something that shouldn't be ignored ;)
Lakes attendees will be aware that I never travel long distance without a spare one in the boot... ...once bitten ;)
-
Thanks guys, another crank sensor it is then!

Do you have a TC or know anyone who does....big, big savings fella. :y
-
as its under a year old.....try the guarantee route :y
-
I do have a TC, I got it last year and bought a crank sensor (among a few other things) It expires this month so my sensor must be less than a year old.
I didn't realise these things came with a 12 month guarantee?

Yes, Genuine VX parts, minimum 12 month as I understand it.
They may do it in several ways I beleive..
such as :
you buy a new one, and return the old, they send for testing, if faulty, you get your money back.
they charge for diag, if faulty, diag is free, and replacement part given.
either way, or another, try it 1st, youve nowt to loose :y
however dont expect to drop an old one on the desk, and walk out with a new one without paying.
If it was me....id prob take the old part in, with its invoice, and say its faulty, id like it swapped under guarantee, see what they say

Had a new Vx crank sensor go in mine in around 2 months. Car wouldn't start, code 19. Replaced with new Vx and fired up straight away - swapped back to "old" new one - no start.
Took it back to Vx under warranty - they said would need to see car with it refitted and if faulty would replace foc - onus on me to get non-starting car transported to Vx dealer (some 15 miles) - no brainer - just fit new and put it down to experience!!
So much for sale of goods act!!
-
Just checked my invoice, crank sensor was bought on 23rd July last year.
My car is running, its just very rough, but I wouldn't want to drive it anywhere with a faulty crank sensor for obvious reasons, I've been there before. My stealer is about 10 miles away in Northampton.
I'll phone the stealer tomorrow and see what he says. I need a few other parts anyway. (HBV, Brake sensor, AntiFreeze etc etc etc)
-
I'm in Northants - who is your stealer?
-
W Grose
-
Ok - hope you have better luck with them - mine was York Ward & Rowlett.
-
Just as Dbug said. W Grose also said that to claim on the warranty I had to take the car to them and pay £40 for half an hour of labour for them to check the sensor on the car before deciding whether to fit a new one under the "guarantee". They say they cannot check a sensor off the car. I say, they don't need to check the sensor, this is a known problem, I've described the symptoms and given them the fault code and I should just be believed and refunded.
Essentially, this means there is no guarantee because it would cost at least £50 to get someone to tow the car to the dealer. As far as I am concerned it's a neat and deliberate get-out of servicing the warranty on a part well-known to be unreliable.
So, I just bought a new one, under protest, but I think this is a matter for trading standards. I am going to write to the guv'nor at W Grose and give them a chance to refund me first and if not, I'm going to war.
-
Thats bang out of order. Like you say, they know its going to cost you money to prove your case so they are probably used to people paying up.
Does anyone have access to Vx "Service Bulletins"?
-
buy new.....fit at home
drive to garage
refit old one...
get diags....and refund :y
refit new one
bit of a pain though
-
As it turns out perhaps VX dealers aren't so daft. My new crank sensor hasn't fixed my misfire at all. (On the bright side I now have a spare crank sensor.)
As I have said elsewhere I now suspect the Dis Pack has been damaged by a long standing slow coolant leak. As well as changing the crank sensor I changed the HBV, cleaned the breathers and renewed the fuel filter but stupidly, forgot to check the DIS pack while the plenum was off. Now I'll have to do it all again.
But if my DIS Pack isn't showing signs of corrosion where do I look next?
The car misfires on tickover, has no pull through the gears and struggles to climb hills.

Could it be MAF?
