Seemingly Random Engine Flat Spot Problem When Accelerating
Dietz replied to skymast's topic in 996 TT, 996 TT S, 996 GT2
Had the same problem - just coming on trottle or the same for just coming off throttle the car would feel "sluggish". Replaced MAF, plugs, reflashed to stock, checked diverter valves, check for boost leaks, just about given up - then heard the suggestion of the coil packs. Had them change out all of them - 7 day delay - not in stock from Porsche. All I can say is that - that was it! Totally transformed the feeling of the car. Perfect now... Good luck - hope you find it. Deetz.
