Just replaced both of the o2 sensor's and all of the exhaust gasket's because I had a p1133 code now the code is back. What can I do to fix this problem for going on again could one of those 02 sensor be bad or dirty?

check your fuel pressure should be 41-47 psi then have a pro look at it or look for damaged wires to sensor in front of converter. there are some tests that have to be done with a pro scanner.
