Caution with the electronic MIL simulators.

You will FAIL an OBDII inspection if you have one. The electronic mil simulator forces the ECU into a constant not ready state and the OBDII inspection computer picks up on that.

The mechanical solutions will pass but they tend to be inconsistent.

not true a good O2 sensor will show a varying voltage in the range that is needed to not through a code. I have pass Il state OBD2 emisions twice with O2 sims and we have had OBD2 scans a lot longer than NY has. I personally use Casper but they hate snow and cold weather

No problems for me with the anit-foulers, Done it on 2 different cars now without any issues. It works and its cheap and NO splicing.
