Do you get KOEO codes? For no codes you will need to run pinpoint test QA, which requires a breakout box. I can email you a copy if you need it.

Are the KOEO condes a pass? Are you sure your following the procedure correctly for the KOER?

You can buy them but there $$$, maybe you can get a loaner at a parts store.

I get a code 67 KOER and 11 for memory -I had a code 14 in memory replaced TFI module with a good spare and it hasn't come back after I cleared memory. For KOER codes I warm O2 sensor for a min or so at 2000 rpm shut off motor wait 10 sec start motor and plug in jumper wire- I hear a click and rpm changes- I take it this is timing check- then nothing happens

Dogg I thought the same thing-look mid way up the block toward center there is a sensor there. Thats where mine went. Guy who did my engine swap (mistake) missed this among other things. I knew it went somewhere it was too clean. There is a single wire along side this with a barrel shaped piece of plastic on the end-no idea on that one -my old 89 Taurus 3.0 had the same thing- is that what you're talking about? I had to feel around to find that sensor

Ken I got KOER codes going. It was that code 67 I was getting no voltage at pin 30 on PCM harness w/ trans in park. Chased wire and found a break at the diode inwire loom at driver side fire wall. Code 67 can cause no KOER - I learn something new every day! I'm beat it's late I'll pull codes tomorrow, let you know what I get

The ECU thinks your lean so its adding fuel, that why you get the black smoke. Start by checking the O2 wiring, then run the pinpoint test, if you need a copy let me know.

The new O2 sensor was the problem. I checked wiring and it was OK. I was not willing to replace PCM yet so I went back to sensor. I checked it on the workbench and it lost voltage when I kept flame on it for 20 sec. When I took flame off voltage went up. Voltage dropped when I reapplied flame. Without flame voltage stayed up. Don't get it I didn't use sealant on anything.
