To give a little background information this is an 02 V8 with just under 80k miles on it. I had the valve cover gasket issue at just over 50k and had that fixed, now im not sure if they did one or both but anyways. My main symptoms are intermittent sluggish acceleration/hesitation which is mostly noticeable under heavier throttle but not always. It just doesn't seem to rev smoothly, it will kind of stick sometimes and then all the sudden break through and the power comes on again. It feels similar to when i had the gasket and coil problem but not exactly, it's doing a lot more strange things as well this time. It also has a signficant shudder when reaching torque converter lockup around highway speeds, atleast i believe thats what the torque converter is doing when the engine settles in for cruising? I'm no car expert. In any case it doesn't happen very often, perhaps a couple times every 100 miles. Also a couple times it had a real rough/shaky idle when i came to a stop but only did that a couple times and went away. I recently went to a slightly more agressive tune with my Xcal but that was a couple thousand miles ago and this problem just showed up. Any chance this is related to the tune? Anyways just wanted to see if anyone had some thoughts or ideas about this before i bend over for the dealer.
