Hi. A couple of weeks ago I had the breather mod done on my Cav (see below) by a Vauxhall dealership (they cleaned out some pipes too) because my car kept stalling at low speeds and when I stopped. The car now sounds better than before, and seems to accelerate a bit better.
However, today, I was driving through town and came to pull up at a roundabout (after about 20 mins of driving). The clutch was in fully, and I'd chaged into 2nd gear, when suddenly the engine died and I found myself wrestling with no power steering.
I started the engine back up and the battery light came on red, but very dimly, and the sidelights and insturment lights seemed quite dim. I got round the roundabout then put my foot down. The faster the engine got the brighter the light got, till at about 3000 rpm it then went out. This was followed shortly after by the engine control indicator (engine management light) coming on for a brief time, then going out, then coming back on for a couple of minutes.
I left the car parked for a couple of hours and then drove it home through town (another 20 mins or so). There were no hints of any problems on the way back.
Hmmm... Does this mean that perhaps my alternator is playing up or something? I've had a look in the Haynes manual for the car, and in the Vauxhall driver's manual, and it suggests the battery isn't holding charge, or being charged. I tested the battery with a multimeter about three or four weeks ago, and it seemed fine at around 12.5 - 13 volts.
If anyone has any suggestions on what might be going wrong, they'd be most appreciated. I'm loathed to take it to a garage again if it can be helped!
What is the lambda sensor? I just looked in my haynes manual and it shows the oxy sensor is located near to the exhaust manifold. I'll go out and have a look to see if it's connected. (sorry to be thick, but are manifolds just pipes?!)
Just had a look under the bonnet, but can't see the oxy sensor anywhere. Not really sure where to look for it, apart from at the front of the exhaust system (or so says the Haynes manual).
Do you know what the sensor's power lead is connected to, or where it leads so I can trace it back to the sensor? In the C16NZ engine, it seems the sensor's leads are connected to the cooling fan motor at the front.
