Our '93 SSEi could have caught fire too, but not because of the intake/PCM problem, and we were very fortunate - in our case, one of the tranny fluid lines ruptured just as my wife (and baby) arrived at their destination and saw smoke coming fron under the hood.
If it had caught fire, it probably would have burned to the ground.
We now carry fire extinguishers in both of our Bonnies.

The rupture occurred because the plastic hose retainers below the radiator allowed one of the hoses to snap out of place (rearward) and rub on a nearby piece of metal until it cut through the hose.

I used a cable tie to fasten the tranny hoses to the plastic retainer so they can never come loose and do that again.

Bill, has yours had both lower trans lines replaced? If not, you can still suffer the fate I did. The factory crimp where the rubber hose meets the stainless steel fails.....that'* how mine almost burned to the ground. I know 92/93 had this problem, and GM changed vendors for the hoses as a result. Both hoses cost me about 40 bucks from the dealer, and about an hour to swap.

Yes, both hoses were replaced by the tranny shop not long before the leak - the tranny had been replaced with a SRTA unit. To my surprise, when I told the owner of the tranny shop what had happened, he said he'd never heard of that happening.

And both hoses had also been replaced on my '92 along with a SRTA unit before I bought it.

Do i need to worry about this? If so what can i do to prevent it? I'd like it to be free...

go to your dealer. Give them your VIN, and have them search to find out if your car was serviced under the recall. If not, find out if you can still do it. The Rat may be able to shed more light on this.
