Hello,
Where to i begin? I have a 1997 (R reg) vauxhall vectra with 119000 miles on the clock (still a few miles left in her surely?!).
The problem started with the EML light coming on while starting from cold, the light would flash for around 5 minutes and then go off. While the light was flashing the car had no power (0 to 60 in 3 days kinda thing!).
The EML light is now permanently on. I have changed the MAF sensor, which made little difference, and the EGR solenoid, which again, made very little difference. I also cleaned the EGR valve, it was coated in gunge, which did make a difference (i can now go VERY slowly up hills). The car drives Ok but there is a lack of power and the car will not rev beyon 4000 - 4500 Revs (Could this be the Cam sensor?)
I had the codes read by the RAC which indicated a turbo boost pressure sensor issue, i also cleaned this sensor (again full of gunge) which seemed to make a difference to the power but still EML light is on.
However, i purchased a code reader and it does not show any codes at all, since i changed the MAF and the EGR solenoid, however, the EML light is still on? My code reader does tell me that the EGR monitor continous check is incomplete?
I am completely baffled by all this and would really appreciate some help from some knowelgable person.
Thanks,
Peter

Lots of issues with the vacuum system on these beasties. You will need a vac gauge and some small bore tubing and windscreen washer T piece to check (about a tenner from accessory shop).Starting at the vac pump with the engine running, disconnect the rubber elbow and check for about 20"+ vacuum. If no vacuum pump is U/S (but you should have noticed the brakes are rubbish)If vac ok, plug the rubber elbow back in and check vac again (using the T piece) and if the vac has now disappeared or is very low follow the vac lines round to see if there are any disconnected or split connectors. If not unplug each vac hose from its actuator and plug it with your finger and see if by blocking one the vac rises.
Other common prob is a partially blocked catalytic converter which will flag up an air mass meter fault. Drop the exhaust off the manifold to prove.

Andrew,
Thanks for your reply. I need all the help i can get ;O) I will try your suggestion at the weekend when i can get the gauge etc. However i have tried disconnecting the vacuum hose from the EGR valve and (very scientific) the vaccuum from this hose when held to my finger does not feel vert strong. I have just replaced the EGR solenoid (is this the same as the vacuum pump? It is located beside the battery.) so i think this component is OK. Thanks for your help. I am not much of a mechanic but am currently skint so i need to figure this out with some help!!
thanks,
Peter
