Do you have the 20V engine? Angela's '90 90Q20V does the same thing.
After the dealer replaced the bomb under warranty, the time got shorter
(maybe 30 seconds instead of 60), but it's still there while we roll
down the driveway.  It seems to just be a foible of these cars.

Again, Angela's 90Q20V is doing the same thing. I've checked the ISV, no
luck. I'm thinking it's the deceleration switch on the throttle, or
maybe a fuel pressure problem?  Does your car stall at all? Hers does,
especially when rolling to a quick stop.
