I Just Installed brand new Denso O2 sensors from NAPA. Car seems pretty good. Log looks like they are oscillating. Please take a look and tell me what you see.
Thank You Guys for all the great advise.

FYI all wires are routed far from damaging parts.
Also just found a ground that i have never seen before at the Cooling fan harness and pulled it and sanded.

Thanks!

Looks better! Keep an eye out for any codes for awhile and you're set .

Those codes are normal when long tube headers are installed. Set the P0133, P0153, P1133 and P1153 to no error reported and uncheck the SES box. When these codes set, the car will go into open loop.

Old thread but I was searching a solution for those two code 1153 and 1133 , instead of delete the code and stilll keeping open loop and closed loop to switch under colder condition , it s not possible to change the duty cycle of the O2 to keep the heater on ? or raise the Temp at which O2 is warm ?? That will cure many idle issues and keep the engine in closed loop . What you think Russ ??
