OBDII codes P0133 and P0130

I have a 96 Tacoma with 275k miles on it and i just replaced both of my o2 sensors and my spark plugs. Now I have these same codes i had be for i changed my sensors (P0133, P0130). What do you think the problem is?

Thanks.

 

Get/borrow/pay somebody with a scanner to erase the codes...when you get a cel, even though you fix the problem you still have to erase the code with a scanner.

Edit: im not sure about obd2 but for obd1 it you unplug the negitive cable for 5-10min it'll erase the codes...maybe try that first before you pay somebody

 

I did erase all codes, after i changed my o2 sensors, then the light was off for a few hundred miles ten came back on.

 

Dunno what those code means, but to clear comp unplug negative cable for a second.

As for what you changed, I think your running lean? Or bad cyl misfire?

Check iignition coils/wires and get injectors cleaned

 

I already cleaned the injectors but ill check up on my ignition coils. Thanks.

 

generally a shop can clean the injectors much better then you can (so ive read, and been told). Also check wires, but it depends on what cyl is giving you the issue.

 

What brand 02 sensor to you use? Im new at the codes thing, but both trouble codes appear to be for the same 02 sensor. Correct?

 

I used Toyota factory o2 sensors and i replaced both my o2 sensors. Yes I think the codes are telling me that the front o2 sensor is giving a slow response. Ima take a pick of what my scanner is telling me.

 

I certainly dont know the answer to your problem but it seems its not running efficient. So, as mentioned, the fuel injectors would be a good item to have cleaned. You already changed the plugs. Have you cleaned the MAF? Clean the throttle body? That's easy to do. Maybe run a can of sea foam through the gas tank and see if that helps.

Hopefully a Tacoma expert will chime in.

 

I have done every thing except have a shop clean my injectors and clean my MAF. How do you clean my MAF?

 

I had the same problem and I tried everything I could think of to fix it; I ended up spraying some carb cleaner into my air intake and it solved the problem.

 

Some helpful video's on youtube which break things down pretty well.

Straight after the air filter box you have your MAF. Unplug the sensor. Remove the 2 phillips head screws. Remove sensor. hold sensor down and spray a bunch of MAF or electrical contact cleaner at the sensor allowing the fluid to then run down and out. Spray generously. You can get these cleaners from any auto parts store.

 

Ok thanks. I did notice that my intake tube has a crack in it, and i do know it is bad. But will that cause these codes to come up?

 

if the system is getting to much air, or not enough vaccuum pressure yes.

 

Ok. thanks guys. just ordered my intake tube. i used factory Toyota 02 sensors for my truck.

 

Well i replaced the intake tube, and reset my computer. Now the codes have come back. I have recorded the real time voltage readings of both my 02 sensors. Hopefully it will help.
Thanks

 

I am running rich.
EDIT: I figured out that I was running rich. This is how they should work.
