About 3 times in total my car has missed a beat when driving it from cold and just tonight it happened. When I first drive the car from cold the car will be driving along as normal and all of a sudden the car feels like it's just stalled, all the power just vanishes for a second and the car is fine again. It does not cut out or stall just a power loss for a second. No lights come on the dash, just a split second the car looses power. It may be the cold weather effecting the pannel filter I don't know. I think it's only done this now 3 times, the rest of the time it's fine. I only put up this topic as it's just happened tonight when I nipped out, did not think nothing of it the first time. My car is a 2.2 Sri. Cheers for any info .
