Engine Performance problem
1997 BMW 328 6 cyl Front Wheel Drive Automatic 173000 miles
About 2 weeks ago, my car was driving fine, I came home, and about an hour later when I started it, as soon as I took my foot off of the accelerator it stalled. I figured out that if I drive with my foot on the accelerator at all times, even when I put on the brake, the car will stay on. It has now started idling really bad and sometimes " bucks" when I'm driving. I had a mechanic tell me it was the MAF sensor, so I replaced that. No change. I have another mechanic telling me it is the oxygen sensors and that I need to replace all 4. The BMW dealership tells me rarely do 4 go bad all at the same time, but they haven't looked at the car. I have another mechanic telling me it is the manifold gasket and hoses. Where should I start that will be the most economical? 4 oxygen sensors at $250 a piece plus labor is out of my range, and I'm not sure that that is even the problem.
