I do, I really hate them.
The "check engine" light came on on the way home from work on Sunday and the car was shuddering a bit and being a bastard.
The light came on sporadically for a few days, so I got it serviced and got the fuel injectors cleaned. When the mechanic test drove it initially the light did not come on. When he finished servicing it, he test drove it and the light did not come on. He got me to test drive it as well. No light.
ONE HOUR LATER I go to drive to the supermarket - the fucking "check engine" light comes on again. I tossed and turned all night because I was so pissed that I spent $600 having stuff done to the car, only to have the light come back on again.
So I get in this morning to drive to work. No light. I start to think it might be all good. I stop at a bakery to buy breakfast and when I start the car again - the fucking light is back.
I have since googled Astras and engine lights - apparently it is a common problem and apparently Astras are lemons.
