The other thread reminded me about this on, and thought that i should give an update.

The couple of weeks ago my mechanic dude tried to fit my new lamda, but the old one was well stuck in. Anyway, the wires got trashed in the process, so have been driving around without the sensor connecte, and haven't had the problem.

Once the engine light briefly wasn't on, and the problem came back, but as soon as the light came back on (don't know if it had temporarily made a connection) the problem stopped.

So lambda sensor it is then.

Just need to get the fecker out now :lol:

Pain in the arse this problem. Well i had it in my old engine before swapping into the eg. Brand new lambda and swapping over to a chipped p28 stopped it permanently.

As mentioned above unplug o2 sensor see if problem inproves as it will be ignored.

Check all the basic stuff like spark plugs leads connected well with no corrosion. Dizzy cap and rotor. Check ignition timing.

Just wanted to do another update on this... Used to get the problem loads when there was a lot of standing water on the roads, but since getting the new o2 sensor on, and all of the fecking rain we've had recently, I haven't had any problems at all :)
