P0171, P0174 CEL after seafoam?

I would clean the MAF sensor, then battery reset before spending money on new 02 sensors. I don't think you can clean O2 sensors.

I did this. Still ran sluggish and hesitates afterwards.

 

So after using more sefoam and two tanks of gas with lucas oil fuel treatment truck is back to its peppy self

 

Interesting. Personally Seafoam scares me and I won't use it. I ran it in my I4 Camry with 95K and it started burning oil so bad that it had to be rebuilt, and all I did was dump one can in the tank. I only had the car for 3000 miles, so was it doing it pre-Seafoam? Who knows, I just won't do that again.

 

I here you. I'm just wondering if the seafoam was the cause or not to my codes and hesitation/sluggish acceleration

For now my truck is running good, so I'll keep my fingers crossed

 

Is this also after you replaced the AFR sensor?

I don't believe seafoam is the immediate culprit. It may have dislodged some gunk and clogged something else but I doubt that it chemically harmed anything. I have used seafoam on several vehicles. One thing I did learn about using it on our 2nd gen tacomas is that you should not use the Brake Booster hose. It dumps all the cleaner into I believe the number 3 cylinder. It's best to use it through the vacuum hose on or directly after the throttle body.

I just got these codes again. Last time was a few months ago while offroading, still not sure why that happened. This time I will scour the truck for vacuum leaks and soak an extra set of O2 sensors in seafoam to try to clean them.
