97 jeep grand cherokee ladedo that stalls and backfires

I too am having the same issue on my 97 jeep. I have made the same kindda repairs. I have also done a tune up and even replaced the computer. It ran great for about a week and then started stalling again. My car guy then said he thinks my transmission might be the problem and referred me to a transmission specialist. Transmission and engine both came back fine and in good shape. I am running out of option. I've pretty much replaced all that is under my hood. I pretty much have a new car with the same problem that wont go away.

Its funny there is no recalls on them. But no answers either.
