    402;406..........402;406

    Several knowledgeable folks I have talked to believe it has to be a bad wire/wires somewhere in the wiring harness. Have the old harness disconnected and almost removed from the car. Once that is done swapping in the replacement shouldn't be that bad. May take some time to get to, weather needs...

    Readings were taken from a digital voltmeter. I only mentioned the scanmaster readings to confirm that there was a change in mv to confirm the ECM was reading what the voltmeter saw. The O2 ground at D6 was taken from the battery ground up front, not from the engine block. Ran tests as stated...

    So if I'm assuming the tests that I ran were to diagnose a Code 13 (that does not exist anymore) the final outcome of "faulty ECM" really does not apply. What it did determine is that the O2 is working as it should, but I still have a fault somewhere in the system that is causing an inaccurate...

    Finally had some time to spend with the car, ran the O2 diagnostic chart and found the following; Step 1 - Open Loop Step 2 - .39 volts (less than .2 preferred) Step 3 - .40 volts (.3 to .6 preferred) Result - Faulty ECM So I changed to a different ECM (used) and found the following; Step 1 -...

    One more item just to confuse things, the car never threw a CODE 13. ESL was never introduced during this whole situation.

    Thanks for the chart, will go through those to see if any of these tests will resolve my issue. I ran some Data Logs just to confirm what the Scanmaster was telling me and you can see the first 4 Logs were from random previous scans over the years just to get a base. The last 7 were taken...

    Have not checked all the splices in the wire harness, but the ground connections at the back of the motor and the one at the turbo bracket have been removed, wire brushed and re-installed.

    Got a set of new PINS from Caspers for the ECM connection (both O2 and Ground) and put on a new Weatherproof Connection at the O2 sensor.

    LT1 with Translator. MAF was changed early on with no change in readings.

    402;406..........402;406

    These are my O2 readings on my Scanmaster. Rinse and repeat 402;406. Millivolts do not change whether in neutral, drive, 800 RPM or 2500 RPM. Car has been down now for 8 months, have run through and replaced all "obvious" parts and pieces (and not so obvious) to try to get my O2 readings back in...

    Wrenching party May 30th @ turbobob924's place

    If I can get up early and get the yardwork done I may have time to stop by to lend a hand. I will give you a call in the AM if I can break free. Paul Brelie

    Help with knock-

    Does it knock if you have it in park and rev the motor a bit, or only under load?

    Hydro boost vs power boost vs Vac Brakes

    The aftermarket Hydroboost set up I purchased comes equipped with an accumulator, which is said to give power assist stopping for a short period of time should you loose pressure in the system. I like the HB, just be cautious from who you purchase the unit from.
