The fact that this one is throwing codes left and right, and often throws conflicting codes, tells me that there is either a problem with the computer or the wiring. First it's reading high on the O2 sensor, then reading low. And then it throws conflicting MAP codes. The VSS feeds the speedo.
I presume 1/4 and 2/4 mean 1 of 4 and 2 of 4?
