Newbie here. I'm not the actual Astra owner myself (I usually hang out on www.mocgb.net myself - can I say that here???) - it is my estranged wifes car that has the problem but I am hoping that someone here can shed some light for us.
Every now and then the Engine computer light comes on and the car seems to go into limp home mode - the revs drop and if you brake too sharply the car will cut out as the revs drop too much. If you switch it off, give it 5 minutes or so and try again all is fine once more and the car will run absolutely fine for a while again.
Seems to be worse after longer journeys and if the driving style is more "aggressive" (quick pull away from lights / roundabouts, harsh acceleration etc) - sedate driving does not seem to exhibit the problem - it has been getting more frequent of late (maybe more harsh driving of late???).
We tried the pedal test to get a diagnostic code out of the car (found by searching here on Friday), however we could not get this to work and the light did not flash at all, alas .
The car is a 1999 Astra 1.8 Auto Petrol. If anyone has any ideas what could be occurring here I would be keen to hear. I had a quick scoot through here on Friday - seems to be a common occurrence but no-one seems to give a definitive answer, although I guess there could be many reasons why it happens.
Some pointers would be helpful.
Thanks in advance to all for any assistance / guidance.
