1995 Astra 1.6 16v Ecotec

Hi,

I have a 1995 Astra 1.6 16v Ecotec.

The baffling problem with my car that seems to elude Vauxhall mechanics and
a so-called diagnostic garage alike, it's the intermittent problem of
revving and maintaining 2500 revs. Switching the ignition off and then
restarting the engine can normally rectify this problem in the short term.

I put a new idle speed control solenoid on, but old Herbie just keeps
revving away. After many weeks of this nuisance I decided to put my faith
and cash in the service of a diagnostic garage. After some time of poring
over the Internet and the yellow pages I decided upon diagnostic expects
Peacock & Purvey and delivered the car into their expert hands.

After two hours of expert diagnostic checks I received a phone call to say
that the fault had been found and that the mechanic was 99.9% sure of his
diagnosis. Now this is the part that I know you are all dying to know, the
problem was the potentiometer (throttle pot) so I paid the bill of £94 and
had a mechanic that I know, fit the new part for less than half the price
the garage wanted to charge me. They were somewhat peeved.

For the first couple of days everything was fine then suddenly and much to
my horror, up went the revs, quickly followed with a cry "why me, I've paid
the bills what more does this bucket want?)

I was not happy that I had paid out £200 and had nothing to show for it, so
I called the garage and they suggested that I give them a £65 down payment
and leave the car with them for up to two week, when I would of course have
another bill for repair and nothing taken off for the money already paid.

Therefore, if anybody out there knows or thinks they know the mystifying
reason why my car revs up, then I would be most grateful for their input. It
should be said, that the engine management light sometimes flashes in the
morning and no fault code is shown (flashes non-stop) also the car sometime
thinks that it's a kangaroo (low revs, low speed, throttle off)

Many thanks

James

Had a similar problem with a vectra and the problem with that was
overcharging.

 

i know this doesn't really help but:
most, if not every msg on here relating to your problem ends with it being
the ICV.
even down to the same rev levels as u r getting.
