This just recently started happening, maybe a few months ago. I have a 1993 Ford Thunderbird and when I go up a hill it drops to about 30-40 mph. I've tried overdrive, drive and first gear nothing works. If this matters, I recently have had my fuel filter changed and I have brand new spark plugs. I do have problems with accelerating (fastest I could ever get the car was 75mph) and problems with the car switching gears. I barely know anything about cars. I just need to know if its worth fixing or to just get a new one. Oh and the accelerating/gear switching problems I have had since I got the car in June 2013.
