Introduction, I own a 2 door n/a 99 gt. 205k miles, still sharp as ever other than a few minor details. The drivetrain is where my concern lies. I have had TWO less than 80k replacement motors.. The original just started running very poor and something just gave... The second one, almost the same occurance. I was driving down the highway, less than two months after the dealer had replaced the previous engine and it just got a horrible top end knock.. Before I could get it off of the highway, something broke, smoke and oil was everywhere. No clue what went wrong.. Was just too pissed to care and wanted another engine. Now onto this one, every so often, on warm starts, it has a rough idle to it. Enough to feel. If I put it in drive, it will smooth out and run just fine. The previous two motors did this before blowing so it has me concerned. I know I am being vague but don't really know how to describe it more so. Any tips? Suggestions? Experiences?
