Default MIL eliminator

pony express mil eliminator, wires in line with O2 sensor get either a mazda or subaru one depending on the colors of your wires, mine works ok, i get an intermittent no signal code, think may be the wiring. next im trying 2 spark plug non-fowlers (basically spacers male threaded on one end and female on the other) stack em drill out the outer one to clear the dome of the sensor, put the O2 sensor in there and put the whole thing back in the test pipe, it moves the sensor out of the main stream of exhaust. there are a few posts on it, i guss it works quite well.<ul><li><a href="http://www.ponyexpressperformance.com">http://www.ponyexpressperformance.com</a</li></ul>
