98 2.0 Misfire/stalling - pug1465
My Pug 1998 GLX 2.0i has started to misfire or seeming to stall when running. The engine appears to stall and then fires up again immediately and gives a real thump in your back when this occurs. It is random event and can be once a day or a number of times on one journey and then the symptoms disappear. A Pug mechanic could not trace any malfunction with his equipment.
Mileage is 101,000 with regular servicing and usually fill with BP unleaded.
Any ideas as to the next steps I should take would be much appreciated as the mechanic seems to think it may mean a new ECU (ouch) which I would like to avoid if possible
