So my car is on the fritz and won't start. The mechanic says that the computers on the 200QT's are notorious for going bad. He also says that the issue is that the computer is fine except for the portion that controls the ignition. There's no spark going from the computer to the ignition apparently. So what I'm searching for is either a new computer or an aftermarket ignition controller, if such a thing exists. During my search i've discovered a few for a 4k, and i was wondering if one of these would work, and exactly what parts i really do need. If you can help me out, feel free to email me, i check it more often than i'm on here.
