This isnt about a mustang its a '97 Mountaineer. Its had this problem for a while now but it seems to be getting worse. Everytime I hit the gas the car just has no power for about 2 seconds, then all of the power comes back just like normal. No matter when I hit the gas it always has this hesitation and half the time it backfires then. Can someone please tell me what could cause this and set me in the right direction?
