i have 2004 automatic transmission zafira 1.8. i had a problem that it started with varrying revs and juddered when put into gear and some times moved very lazily. may be going into limp home mode. my technician said it is the problem about spark plugs and ignition coils. i have changed them but now it has got worst. i starter but just gets switched off in the next ten seconds. i am unable to even move it because it is never staying switched on. i put back the old spark plugs and coil as well but problem persisits. if somebody can help me on this matter?
