99 2.0 Smoky exhaust, cockpit ecu light - Ell's
Right 1st, hope someone can help before these small probs become 1 big one,
2nd, please bear with me as there is a lot I'd I like to say, so as not to have to backtrack later thanks

Ok so I bought my vectra 2.0 sri s reg 99, just after xmas with no obvious probs on the test drive.
After a week or 2 the exhaust started to smoke (white) but i'm not loosing any coolant, water, oil, e.g..
Plugs were dry but Iv popped in new ones and HT leads. Any help welcome

Also I have the engine management or ecu light up in the cockpit ( amber, pic of an engine with flash in the mid )
I comes on intermitted, the revs will drop off if I give it some welly they will pick up again but now and again it will stall
and not turn over again for a min or 2. I've used electric spray on all connections and looked at sensors. But with out
a haynes book i'm not to shore wots wot.
I also have tried to find the ALDL connector so I can do the old paper clip test, But I've looked at all the pics andread all the info on www.topbuzz1.carenthusiasts.co.uk/info/fault_codes...m but cant find it on my motor

I might be a bit thick and my car is to old! But any help please!

The diagnostic plug is under a removable cover just below the handbrake lever.

Re the exhaust 'smoke'. Are you actually sure it's smoke and not steam from the cold weather we've been having recently?

Might just be a knackered Lambda sensor, the fuelling would probably have gone rich as the sensor was failing, once failed it'll run on a static fuel map if the sensor reading is out of spec and the fault lamp will be lit. Don't drive it like this or you will kill your catalytic converter.

Once you've fixed it do a couple of miles on the motorway in 3rd gear to give the catalytic converter a good clean out.
