Seems my warning light came on this morning, and the car stalled (was in netural rolling towards a red light) that was not good, took the tuner for a run for about 10 min... and not ONE hic-up...
Feels like its only doing in while the car is cold, I'm starting to think the O2 sensor is going berko till the car warms up, drove home and was fine after about 5 min (though light didn't come on at all)...
Leaving it with the tuner next week so he can check the cold start and let him feel for it for himself...
