Car starts hard, idles great within minutes. Misfires when accelerator is push down fast. Slowly depressed it will go to 2000 rpms and then misfires again. Goes no higher. Codes that came up are PO130 and PO135 refering to the O2 sensor right bank. I replaced the O2 sensor right bank, plugs and fuel filter and have the same results. It now sits at my mechanics and he is stumped. Cylinder # 1 plug was semi fouled but not bad when replacing plugs. Could that particular coil be bad? Thanks for the help. Brian
