Given they said they did not connect the up stream o2 sensor because the wires weren't long enough it sure sounds like the wideband was either not connected at all, or it was placed in the down stream position where it was useless.

This combined with the abuse did the car in.

I should have said it would run like shit. Bu you get my gyst
