I am new to the forum and feeling my way around at the moment!
My Panda 4X4 twinair has just been serviced (oil and filter change) and ever since over the last week my engine warning light comes on! (I get my car serviced once a year and do just less than 5K miles). This is after a few minutes from a cold start and driving less than a mile the engine suddenly loses power. This is when the engine warning light comes on along with the warning triangle. After a while and a number of restarts and I guess when the engine is warmer everything is fine again, even during stops when the car maybe left an hour or so. The problem then reaccures the next day from a cold start. Hope it is not the cat and my local garage is mystified at the moment as well.
Thanks in anticipation

Welcome. I have same issue. First time it happened it cleared after 4 days/140 miles. Most recent time limped back home about 250 yards. Restarted for my Dad fine and he gave it an Italian tune up which seems to work. Main dealer told me the car doesn't have to adapt to fresh oil. But there's something it doesn't like. Hope sort soon. ?
