i got a 98 1.8t auto but cant get it to run right anymore after i installed some mods. its a giac chip but i did change to the more aggresive n75 valve but i changed all the coil packs, plugs, maf, icm and im still misfiring. i searched but i guess the last thing i should try is bad connections? but after i installed new plugs and col pcks it ran fine for 2 days but now its worse. maybe a defective icm they gave me? any more suggestions thanks..........
