Hey I'm in need of some help. My 84 regal was running perfect the whole time for a while and now when I drive it once it gets to 40-45mph it doesn't go past that and once it gets there it just stops speeding up and just hesitates till I slow down. Anyone know what it could be? Need more info of the problems or of the car just ask. Trying to get this on the streets again :/. Thanks.
