Clouds of black smoke gone 700

posted by  someone claiming to be riverol on  Sat Mar 2 06:47 CST 2002 [RELATED]

A few days ago, I reported clouds of black smoke upon accleration, particularly driving uphill in the mountains. The car is an '86 760T which had been running very well and on which I had put a Dawes device a couple of days before. I removed the device, but clouds of smoke continued. I read O2 sensor voltage and found a constant .87 volts at idle after I drove the car for 15-20 minutes. I thought I had poisoned the O2 with silicone I sprayed on turbo hoses to put them back on the car after some fiddling. Some at Brickboard thought the Dawes device had blown a turbo hose, but these are new and checked out OK. Last night I checked O2 voltage and it fluctuated like it should. Today, I drove the car and it ran perfectly. Is it possible O2 sensor had a mild case of silicone poisoning and has now cured itself, perhaps cleaned off by exhaust gas and heat? I have a new O2 sensor and FPR in the mail from fcpgroton. Should I install these anyhow, since most other fuel injection, ignition and fuel delivery components and sensors in the car is now new, but O2 sensor and FPR are original as far as I know? Best regards.
