I think an expensive problem is arising. 2 days ago my astra started chugging for a split second at a time, the gaps between it doing this were quite random and didnt really make much difference to the drive.
as usual it gradually got worse and yesterday i got so bad that the car stalled and wouldnt start without flooring the pedal, even then it seemed to hesitate. i had to rag it home keeping the revs above 3k.
I started the car this morning and it seemed to idle fine then when i hit the gas the revs dropped almost to the point when it stalled and then picked back up.
the exhaust pops and splutters when the problem starts.
the car pulls to 100 but still splutters on the way and loses power now and again.
i changed the spark plugs earlier and they were covered in oil, burnt yellow and the electrodes were burnt down quite a bit considering theyr only 3 months old.
after the plugs were changed it ran fine for about 20 miles then it started spluttering again.
Please help its, really frustrating when you know theres a problem but have no idea what it is.
