ok here goes, while driving above parking lot speeds my 1996 (with2.0 98 engine) escort seems to be jerky, the a/c is not on. as soon as I shift into second it seems that it has a hard time wanting to move, 3rd gear is worse, it is drivable but I'm afraid that if I continue down this path my engine will explode. Any ideas what this issue could be? All the vacuum lines are connected and it idles smooth, could it be something as simple as a fuel filter? I'm lost as hell and I could really use the help, thanks!
