I did the search, so decided to ask the question. My 93 Cobra, Mods are KB2.1 Flowzilla, MSD distributer and Coil, everything else is stock, well cam from a 89 5.0, but everything else stock Cobra. I have bucking and jerking at slow speeds with light throttle. More noticeably around 1500 RPMs. Good acceleration, but once it reaches speed and cruising, I can feel/hear a skip here and there, but worst at low speeds. One more thing it does, while normal accelerations, once it reaches speed, it seems like everything stops as if I remove my foot off the gas, very noticeable, like it is hitting a limit or something. In third gear it is the worst, I go through the gears, hit third, once it reaches a point where the acceleration should stop due to throttle position, it seems like it just hit a headwind, like instantly. I don't know what is causing this. I have new plugs, wires, IAC, and TPS. Reset idle, TPS at .96. Also cleaned the MAF with MAF cleaner and cleaned the throttle body thoroughly. VAC holds steady at 17-18. I tried looking for vac leaks, none to be found (used the propane and carb cleaner methods) It idles kind of roughly, it will skip here and there, but sometimes it will stumble so bad, it will almost die, then rebounds. sometimes I start it and it will die instantly. If you experienced this, chim in and let me know what you done to fix it. My next step is to pull the dizzy from my other cobra and see if the MSD distributer or coil is giving me the issues. After that, maybe putting in my 60lb injectors and remove the 24s. Any help is appreciated.
