miss fire

[sponners]

what sort of reading would you suspect.....if it's only breaking down when hot....put up a post around this sort of thing only happening to mine at 6000rpm....don't think its the plugs, but maybe the coil packs...

What do you think??

I can see people are having pretty good success diagnosing the coilpacks by measuring the resistance across pins 2&3 on the coilpack plug.

should read about 1.3-1.4kohm

cars with issues seem to be getting readings around 0.5-0.6kohm.

is 2 & 3 going clockwise starting at top left? (i believe there are 4 pins are in a square formation or am i wrong?)

mine did that stutter/missfire thing the other day again it only seems to happen after im hoofing it, stop, then start again so think its affected by heat also..

 

[sponners]

there is only three pins mate (second and third)

I agree, there should only be 3 pins

must have misread something then, oops!

forgive my ignorance as i haven't actually got under the bonnet to look at them...but are these pins really obvious or is there a pic somewhere...

When you remove the Plug Cover on the Rocker Cover buddy you will understand what we are talking about.

can i just check im doing this right, hopefully will help the op too.

is this multimeter set correctly?

pins to bridge, starting from the left, 2 & 3

reading im getting, was 0.77 but has been gradually dropping, presume as its cooling?

if i have done anything wrong please tell me.. actually confirming if its correct would help too!
thanks.

i think clintons problem was just a low fuel level! hope he will be alright!..anyway..regarding fuel,,does anybody tried the momentum99 unleaded in tesco?..any suggestions,coz i tried using it for 3 days...it's a bit alright plus it stay's longer compare to v-power..pls correct me if these momentum99 is safe to use or shall i stick to v-power

yep thats right mate, looks like the packs are a bit poo, do you have some you can borrow to make sure......but either way looks like you need some better ones.

(I've just checked an old set of mine and they both read 1.5kohm, so yours are definately over the hill)

yeah the tesco 99 is fine, just as good as vpower......and cheaper

wicked...Tesco 99 here we come...lol..and club card points...lol

cool, thanks sponners, ill get looking for some new ones then

the only thing i found with tesco 99 momentum is it burns it quicker than v-power and also pops more from the exhaust!

 

[ron23]

well thanks guyz for your ideas re: tesco momentum99 or shell v-power..i think both are just perfect for our engines..
