Astra - engine rough when warmed up - Success!

Thanks to all who helped with my original problem: posted 30th January

my '97 Astra 1.6i 16v (Ecotec - DOHC) is idling a bit rough when warmed up,
and
hesitates when accelerating. This doesn't happen when engine is cold,
though.

Problem solved with new set of ignition leads.

By the way, Here are VX dealer prices I was quoted:

ignition lead set......£143 + VAT .... yes - £143 !! (isn't that taking the
p**s for some rubber/conductor/connectors)
DIS module...........£188 + VAT

Luckily I didn't need the Distributor module, Autovaux didn't have the
leads in stock and I have to make a long-ish trip next week, so just bought
a set of leads locally for £21 - not as toughly made as the original, but
working fine for now.

The ICV is under the inlet manifold on this engine, Haynes manual says to
access it from UNDER the car, hope I don't ever have to do that !

 

Blinkin flip....that's even more expensive than I was quoted for the
Omega...mind you the Autovaux leads I bought a while back only lasted
40K, I swapped back to the original 120K + leads when I had exactly the
same problem the other week.

 

I was lead to believe that the Autovaux leads are original equipment - not
cheap aftermarket ones ?

they quoted me £40+VAT for a set, which was around £100 less than the Vx
dealer.

ISTR from many, many years ago that the Vauxhall leads had the heat
protection shields on them whereas aftermarket ones tend not to but
they're still not worth 143 quid.

 

I believe the Autovaux ones are made by Beru, same as the GM ones; the
only differences I noticed are that the autovaux leads are a bit
lighter in colour, slightly different lengths, and don't have the
little numbered tags on the end to ID which lead is which. I'd probably
risk another Autovaux set if necessary, given the huge price
difference. :-/

 

yes, I took the heat shields off the old original set and put them on the
new cheap set.
The rubber housing around the connectors is certainly not as solid as on the
originals, and I would have bought the Autovaux set, if they'd had any in
stock, perhaps I ought to order some now - just for next time ??
