I have a 96 12 valve 5spd and all of a sudden it wasn't going to full fuel when I would get one it. I found that the intercooler was rotted out and leaking so I replaced that, but it is still doing it. It doesn't act like it's getting air in the fuel it idles and runs fine and has power on the low end but about 2,000 rpms it gets supper sluggish and I also noticed that I've lost about 800 rpm when pedal is to the floor in any gear. I took the afc housing off my 98 and put on it but it didn't change anything I'm out of ideas......
