Engine Performance problem
1996 Volvo 850 4 cyl Two Wheel Drive Automatic 135000 miles
I got this car about 2 years ago. When I test drove it it was fine. Two days after buying it I seen black smoke a couple times and then nothing for about a year. Then the black smoke started again. I took it in and they told me it was the oxygen sensor. I haven't replaced this yet, could this really be what it is? The car now puffs black smoke any time there is any kind of hill or anytime I even press on the gas at all. It also loses power when it puffs black smoke. Sometimes letting off the gas and then pressing again makes the smoke go away. I don't want to sink $150 in a sensor if it is really something else. What do you think. Thanks for any input.
have the same problem?
