So i just bought this vehicle from a friend and i had a few vaccume leaks in my power booster so i got those fixed and on the way home from the mechanic it dropped mph on the highway all the way home. It just would stop accelerating even though i was pushing the gas pedal it would jerk and almost stop as slowing down then it would jerk and accelerate again. It got so bad that i puttered it home and took it to a shop and they called and said its a timing chain issue and my motor is going bad on the inside and it would cost more than the car is worth to fix. I went to pick it up and it drove home just fine. I love this car and its been fine up until now and i dont think its the motor but im clueless. Anyone had this happen ever or know about it?
