Vecta - Engine Management light ????

Oct 16, 2004 2 Replies

Hi i am experiencing some problems with my vectra. Basically the car drives fine, but then it will suddenly jerk for a couple of seconds, then the engine management light appears and the car drives fine again. Does anyone have any idea why this may be, and what can be done to fix it? I am worried that this may lead to causing a bigger problem with the car.



Thank you.


Hi,

Does the engine light stay on? If so, it's running in 'emergency program' mode which won't be the most fuel-efficient way of travelling!

You've got 2 choices:

1) Take it to a garage and let them plug their fault-code reader in and find out why it's unhappy. This will cost about 20 quid.

2) Read the fault code yourself. This is done by locating the ECU diagnostics plug (it might be under the handbrake trim) and shorting a couple of pins on it. This makes the engine warning light blink a sequence that tells you what the problem is.

There's a few web sites that detail option 2. Here's one to get you going:

Observe the warning notices it contains!

I've had the same problem only the engine management light stays on for long periods while other times it will not come on at all. I also have a "clunking" noise coming from the underside of the car. I first thought it was the shocks, but it wasn't. Turns out the Cat Converter inside my exhaust is breaking up. Quite common in vectra's so I'm told. The noise is terrible. I think the two problems may be connected. When the EML comes on in the first place the car only loses a small amount of power but when I've been driving for say an hour and the light comes on and the power loss is significant. Embarrasing at times when you get overtaken by artics on the M/W. I'm getting rid of mine anyway, a mechanic told me to replace the Cat Con is well over £300. F*ck that....I'll get a new car.
