## Description

Review: Works like a charm - Get a spray bottle from Home Depot.unplug mass airflow sensor. (The engine will stall if you don’t) remove the hose to get access to the intake. Have someone rev to 300 rpm. Spray the whole bottle. It takes about 5 mins. Reinstall the mass sensor. Clear all the codes.Go drive 30 mins in highway speed. Go to inspection if no light comes on. Good luck

### ⭐⭐⭐⭐⭐ Need a sprayer
*by R***Y on June 8, 2024*

Used in a 2012 Prius with almost 300,000 miles, the cat below threshold DTC light was coming on. I put this through the hose from the valve cover before the throttle body with a small pump up sprayer I got at the hardware store, while it did look like it was cleaning gunk out of the cat it did not solve the problem, the light continued to come back on with the same error code. I took the car to Toyota and they are in the process of installing the 2 new cats they said it needed, about $2,500 here in California. I also used it in a 2003 Chevrolet Tracker 2.0L with about 85,000 miles and no CEL. I was able to use some clear tubing to hook it up to a plugged vacuum fitting after the throttle body, I did not see anything coming out of the exhaust but the car seems to have better acceleration. I bought 3 bottles and poured all 3 in the sprayer. Still have some left for next time. Seems like a good product though not always a cure all.
