I have had my cars almost two years now and up until the last week it was a weekend toy. Any time I drove it, I drove it pretty hard and was never disappointed. Car runs strong and I have no complaints there. However I've now started driving it more regularly, and have been driving in conditions more typical of everyday driving. Traffic and interstate type stuff vs strictly back roads. I've noticed that under certain circumstances, the car will have a slight stumble/hiccup/glitch under acceleration.
For example….rolling along in 3rd gear or so….traffic briefly slows down so you let off the throttle and start coasting but not enough to require downshifting. At around 1200-1500 rpm or so if you moderately roll back into the throttle to accelerate back up to speed, the car will stumble or hiccup slightly before pulling away. Yes-I realize this is not the car's peak power band or even close to it. I'm also well aware that this may not be the most efficient way to drive. These cars are not low-end monsters but they still have plenty of power to accelerate back up to speed without downshifting in these types of everyday situations. It's also pretty inconsistent. Sometimes it reacts fine under these conditions. The car is Lund tuned and I don’t know if it did this on the stock tune because I never really drove the car in these kinds of conditions before. Is this just the nature of the way these cars perform? I know there's probably all kinds of VCT stuff going on and these engines don’t particularly care for low RPM but I'd have to think the car should run smoother than this? FWIW I can watch my ngauge and the car is always adding timing, even in these conditions. Its not like the car is pulling timing and cutting power briefly, this is more like a brief stutter. Anyone else ever experience this?
