I know the exact problem you guys are talking about.
I have a 2000TL & the original owner of the car have had this problem since it was new. The problem with my car has happen maybe 6 times in the almost 12yrs I have had it. It did it a few weeks ago & the car has 92,000 miles on it.
Acura dealer gave it a clean bill of health when they did spark plug change & Timing Belt/synthetic oil & a few other repairs like hood struts & headlight.
motor mount. The car has always been in good shape in general.
So the last time the car did this was 3 weeks ago. I drove about 3 miles in city early mourning 6:00AM not much traffic. Go to doctors office pharmacy to pick up meds for elderly mother. This was from a cold start-up outside temp about 50s. In pharmacy not more then 15mins car parked in underground garage, Car start up again fine just like from cold start engine running fine & normal. Stop at hospital pharmacy to pick up my blood pressure meds. 2nd trip other pharmacy is about 10min drive normal traffic moving city speed 25-35mph. Park in another garage 3rd level up open to outside. Car is off about 25-30 mins . When starting car to leave it will not start like it is flooded. After 2nd crank it starts but low rpms like said rough idle shaking. Move car about 20 feet out of parking space it then runs normal everything is fine. I did thi once when it was new but did not do it again for a few years. It had been a few years since this has happen. I remember the day it did it in 2007. We were going to pick up the new Honda Ridgeline truck & the TL did twice that day. I took it to the car wash something that I do not do often & it did it. Then it ran normal to home about 15min drive 25mph city speed. Went back out shortly after to renew drivers permit at DMV car okay to DMV. Park outside on street in DMV 40mins max Started car & the problem happen won't crank then rough idle when starts. Drive car a few feet & it runs fine, Like said it may have done it 6 times in the almost 12yrs I have had it. Fuel Injectors were checked once by dealer for other engine problem some years ago but this issue is tricky. If I can recall outside air temps may have been mild when problem comes up.
It may have been something about this on the old Aol ACURA TL .COM forum back in the 99 or 2000. I can not recall what it was but it may come back to me.
