ok i pretty sure the first 2 sensors were just worn out ...... when i got the fluid in my plug for my pcm it started running like crap like when the other sensors went. at any rate it was just the fluid disrupting the pcm. but i still the engine light should come on warning of missing or whatever, it never did when my first 2 sensors went or when the fluid mysteriously got on my pcm plug. i had to put my old pcm back in so the engine light would come on and i could look up the error codes ??? with my stage one the engine light never comes on even if it should. anyway its running good now and i am happy ....... although i am selling it now

cause i bought a sport trac ......... i will miss it ......
