Paul there is a TSB over at the netreg site about this 'quirk' on the 90's. There was no recall issued. Just an updated EPROM as an answer to what you are describing if the customer made complaints about this condition to the dealer while under warr.

I remember reading the TSB and I bought the updated EPROM back in 05 from a dealer, $40.00, and it almost eliminates the issue. It still 'hangs' a bit but returns to normal much quicker than my original EPROM. There is a thread about it here where one of the guys that are into writting their own EPROM's listed all the changes on the updated EPROM....quite an extensive list of changes & interesting reading.
