I have a 97 Thunderbird 4.6 with 131k . The car runs great whenever I just cruise, it gets up to speed no problem, nor hesitation. But any time I floor it, it starts backfiring and hesitates to accelerate. The car has no codes, and I just recently replaced the MAF sensor which I thought was the problem, and it made no difference. Anyone have any idea what could cause it to slug and backfire like it does?
