1st question/annoyance:
This only occurs when starting off in my 1991 SHO, after the car has been sitting for more than about 6 or 7 hours. It happens no matter whether I have or haven't set the e-brake, had to backup out of a parking space or just taken off in first gear. Anytime between the instant the clutch has been all the way released and about 1.5 seconds after release, I get a brief, prounounced crunch, like a very short grind, as though something is slipping into/out of place. It can be felt in both the clutch and accelerator pedals. This is a one-time occurence until the car has sat for 6-7 hours again. The sound seems to emmanate from the drivers side of the engine compartment, but it is hard to tell because I can't stand outside the car and listen. Had a new clutch and flywheel installed in early Nov. 2002, has less than 3k miles on it. I have tried rolling out in neutral, with the clutch released, but the noise doesn't occur until I shift into first, let out the clutch, then crunch.
2nd question/annoyance:
Occurs under similar circumstances as above: car has sat for about 7 hours, I start out moving, shift into second, and all the way through first and up to 3000 rpm in second, it feels as though I have reduced power, as though the e-brake were sticking or something similar. But, once I pass 3000 rpm in 2nd, I have power again, and will for the rest of the ride, through all gears throughout the powerband. Power loss isn't huge, and doesn't feel evident at very low speeds, <10mph.
What could be causing these things to occur? I have searched the forums and haven't found anything quite describing these things.
