Hi,
When I first bought my 1997 Plus 8 in August, the tickover was very erratic and would quite often just cut out. Sometimes hunting or over revving first.
I changed the stepper motor, HT leads and distributor cap, and Matt at Lifes Motors tried a different MAF sensor and ECU that he had on the shelf.
Nothing seemed to make much difference until we changed the temperature sensor and Lambda sensors.
Coincidentally, I fitted Librands manifolds this week and was thankful for the new Lambda sensors.
Now, when started, it appears to tick over steadily for a minute or two, then it is like the engine has been switched off, it just cuts out.
I have checked all the hoses for air leaks, I have tried it without the air filter and I have scrupulously checked the new Magnecor HT leads to make sure they are correctly fitted and not touching each other.

I would be grateful for any ideas on where I can go with this now.

Many thanks, Phil
