V6 stalling/poor running

[stuvaux]

ok thanks

could the seal around the IAC valve cause a leak?

it doesn't seem to fit as well as before i removed it

[stuvaux]

ok,  i've oiled the IAC valve - drove the car, problem seemed fine - but now it is back again!

when the car starts to run badly, at tickover, the instant consumption is at 0.8 gal/hr, where it is normally only about 0.3 gal/hr

also, there is a strong smell of bad eggs(!), which i know is the cat

any ideas?

thanks,  stu

[stuvaux]

could this mean one of the cats is knackered?

or could it be excess fuelling causing the smell?

any help on what to check next woulb be appreciated

thanks

[stuvaux]

still no joy!

not really sure what to look at now
someone said it might be a blockage in the exhaust?

[stuvaux]

please help....

any ideas would be very much appreciated!

i want my miggy back!

thanks,  stu   :-?

...have you checked for any stored fault codes?

[stuvaux]

i haven't yet
as there was no EML, i didn't think the ecu had picked up a fault

i will try anyway...

thanks

[stuvaux]

there are 2 codes coming up -

19 & 135

according to my code list, this is RPM signal (crankshaft sensor) - incorrect signal & `Check engine` lamp - low voltage

does this mean its likely to be the crankshaft sensor?

[TheBoy]

19 = knackered cranksensor  (31 is normal crank sensor fault when engine not running)

[stuvaux]

so definitely a knackered crank sensor then?

where is the best place to get one of these from

autovaux quote £28.17 for the oval type, and £46.83 for the square type

which is the most likely one for mine, a 1999 2.5V6

also, what does the 135 code mean?

thanks

The 135 code was posted a bit above, EML light. I've got a 135 but I disconnect the battery with the ignition on and I bet that's where I got it from.

I think the oval one is the latter type, I also need one. I think the square type also needs a new seal. I'm hoping that by removing the scuttle I'll be able to see what type of plug it is.

[stuvaux]

thanks mate

according to the haynes manual, you should be able to see the connector once the scuttle is off

[stuvaux]

fitted new crank sensor yesterday
car was running fine until today
the stalling problem has started again
it is still showing fault codes 19 & 135

can anyone suggest where i should look next???!

Sorry I have not replied before......

Can you try something.....when it idles badly, can you give the EGR a clonk with a hammer on the metal body.....
