Thread: Troubleshooting Help! p0133/p1133 Slow response o2

I keep getting p0133/p1133 on my car. So, I read around... and I saw all the bosch-flaming going on... so I got a Denso. Installed it, cleared codes, got a new o2 extension.... same thing.

I even put a stock temp 195 tstat in it. (Thinking that since the o2 sensor relies on heat, maybe it was too cold)... but yet I still get it.

Anyone of you guys have an issue like this? These are the only codes im throwing.

I replaced:
2 o2 sensors
2 o2 extensions
2 thermostats

I re-bunged my pacesetters, due to the s***ty location of the o2 sensor, and moved it about an inch or so back, but that didnt help either.

Any ideas?

Anyone?

not sure if this applies but on the camaros for longtubes we would use corvette rear o2 sensors, the wires where really long and didnt require the use of o2 extensions. plus they had a better heating element in them which helps with the increased distance from the motor.

I haven't put in another bung for my wideband so I swap it out with the front 02 sensor different times. I have a new bosch narrowband sensor and at times it has given the code even when it is installed in the car. If you scan it, you can usually tell if its working or not, if the 02 is truly bad, it will sit steady around 430v or so. Sometimes just clearing the code a couple times will do the trick.

If the problem still occurs or if your pacesetters are leaking at the y-pipe, you can weld a new bung in the crossover pipe of the pacesetters near the rear head. The 02's should not vary much from bank to bank, especially not enough to throw off a narrowband.
