Question Engine gone sour...

Is it possible for an engine(3.8 L Ford 1995 Windstar) to go sour just two months after an emissions test(Canada) which it passed. By sour I mean I had it checked by a garage for chugging, stalling and loss of power on the dyanostics computer. They said 14 things were wrong and it was more worth my while to get rid of it rather than fix it. A couple of things they actually told me was 2 cylinders had low compression, oxygen censor was malfunctioning. Could a bad 0-2 censor be the culprit for most of the problems. I think the censor might have been bad for almost 8 mths. I can't stop thinking about it. What if they are wrong. Any suggestions?

Thanks Geeman

You could get a second opinion before deciding the fate of the car.If the cylinders with low compression are next to each other it could be a blown head gasket.I don't think an O2 sensor would cause all of your problems.If you paid them they should tell you all 14 problems,so call and have them tell you.

They also told me that it was over-fueling it self.

So would a blown head gasket just cause low compression or the loss of power and chugging. The power loss is so bad the van can barely make it to 15 mph, and once you stop it stalls.

Blown Cylinder Head Gasket.

Blown Cylinder Head Gasket will cause loss of power,have you checked the engine coolant level lately. Most likely the missing cylinder will be #4. What happens is engine coolant gets on the spark plug and it doesn't fire well. And when this happens coolant is washing down the cylinder wall so there is a good chance that the piston will gall in the cylinder. Plus the Hego sensor code shows up because of the coolant being sent out the exhaust.
