It's fine when I drive it easy but when I accelerate to get on the freeway it sputters/pops making the car slow down until I ease on the gas again.It did this awhile back until I put some lucas fuel treatment in.It ran for a good 1,000 miles until it started doing it again.Any help or information will be well appreciated.I just got my car out of the shop today and this came back to haunt me.

First thing I would look at is a bad ACV, and probably TPS is out of adjustment.

Ignition timing off more than 5* can also cause that.

 

Possible fuel pump or fuel delivery system creating "lean pop"

 

Thanks i'll check that out.I just had them adjust the TPS that's why it was there.
