Had a problem with my CEL popping up after installing a JIC test pipe. Wasn't too excited about doing any cutting, welding, or drilling on it. If you don't want to go the fouler plug rout, this works great and is really easy. You wire it into the o2 sensor harness and it sends its own signal to the ecu. I had one of the wires on backward at first but once I solved that, it worked just as it says it will. Make sure you have a multimeter to test the heater wire. I guessed at it and wasted time having to go back and switch wires. The simulator is waterproof so if you can wrap the wiring in heat shrink, then you don't have to worry about it.

I went with the $4 anti fouler route.. I find it to be the better choice because I didnt have to splice or hack into my harness.. Just my .02 cents.

 

mechanical sel fix, like the fouler are the best choice IMO,

cheap and easy
