I have taken this car to the only two mechanics near New Orleans willing to assist me - PLEASE HELP!!!!!!!!!! The car floods out at anything below WOT. The code reads a 45 - O2 sensor - it has been replaced twice. The brakes fade out - to the floor. Vacuum pressures and compression tests are good. MAF, TPS, O2, EGR, ECM, etc. have all been replaced. Any other advice??????
