1996 Cobra Issues

[Theturk182]

Hello. I am having some issue with my recently bought 1996 Cobra.
Cruise Control is not working. Horn works so I its not the fuse.
At about 3500 RPM the car has a slight hiccup, only when she is clod. Once she warms up, it is gone. Plugs wires have been replace and the plugs look new to me.
The car has 3.73 gears, pro 5.0 shifter, Borla Mufflers, Off Road and a K/N air filter. The car has 98000 miles on it. This is my 8th Mustang and First Cobra. I like the car, but I am not sure if I want to keep it and modify it, or if I want to sell her and get a Terminator instead.
Any help here would be greatly appreciated.
P.S.
I did buy a can of sea foam, I have not used it yet.
Thanks
Seth

Yea the cruise controle could be vacume activated. If you are going to mod it it is hard to get power out of those motors unless you boost them. The heads have cooling issues in cyl 6 7 8 but you probably wont run into that unless you put some good power to it. I would go 03-04 if you can. The 96 motors are just not strong enough on the bottom end to do real power unless you build it. Money and time. Also who are you going to trust with all your expensive parts.
