on a vw polo 1.4 2001 16v been trying to change my spark plugs, kind of
decided to wait till I buy a torque wrench to do it properly as I didn't
fancy overtightening it. Anyway on to the pupose of the post what exactly is
a coil pack and what does it do ?

I've got a Mk 3 Petrol Golf 1.8 CL '94, and on the way into work this
morning it started running unevenly. It got worse and worse, with the
throttle pulsing up and down and sometimes stalling. When I finally
got to work it stalled at the main gate and would not restart.

Have a problem with one of my keys.
Unlocks & locks car ok via remote but wont start the car.

The head gasket has blown on my S reg Renault Megane 1.4 and I've been told
that a product called K-Seal is worth trying as an alternative to a costly
repair, in the region of £380 - £550. Has anyone used this before and does
it work with a blown head gasket?

Does anyone know how to test the various sensors on yer typical petrol
engine? I'm thinking specifically of the air and water temperature sensors,
tps and lambda but I've no idea what numbers/resistance etc. I'm looking
for.

None of the direction lights are working on my Ford Ka - and the
problem is not a fuse ;-)
As far as I can understand the relay is placed in(side) the
"multifunctionswitch" that is placed around the steering wheel (the

Ooops, borrowed a friends car, a peugeot 106 diesel and put petrol in
it.. Fuel guage was in the red, I put in 2.5 litres of petrol and
stopped... Then filled it with another 25 litres of diesel.. Just
driven 25 miles and it seemed fine, faster in fact?!!?

I decided not to go the knackered-car-and-swap-engines route and am now
looking at recon engines.  I have had a quote from Heathrow Engines

plus VAT.  This is apparently a brand new engine, not a recon or

Is there any easy way to read ABS fault codes from a 2003 Renault
Scenic please? I have got an OBD-II reader, but that will only look at
engine data. Is it a software or a hardware thing that I can't see
other codes, or is all that stuff still proprietary? Googling didn't

Thanks everyone - really useful.

went to National tyres as they do a £15 oil change offer and they didn't
have the filter in and couldn't get it until about 6 days time!!!! The guys
said that I needed the Premium semi synthetic oil at £21 for the lil old Pug
106 but didn't seem bothered or interested at all.

Can anyone suggest a reason why my car would be running rough when cruising
at a constant speed - but be perfect when under acceleration or at idle ?
I've already changed the air filter, replaced spark plugs & leads and used 2
tanks of fuel with injector cleaner additives (nulon & ...
