402 might mean that your EGR passages behind your TB are clogged.. try cleaning it out with a bottle of barrymeans and a toothbrush... you will need to remove the TB and get a new TB gasket tho

Thanks...any Ideas how much a new TB gasket cost.
Most of the codes come from the O2 Sensor ( bank 2 ) being shot
