This car WAS running fine. From one day to the next it's performance completely changed. The symptoms are;
- very rough running. (loud vibrating under hood on passenger side)
- serious loss of power. (won't move more than 30 mph)
- idle swings from about 1600 rpm to stall.
- metallic smell from exhaust.
No smoke. Plugs look clean. Turbo blades move freely by hand. All connections (hoses, wires, etc.) clean and tight. (Some folks have suggested a faulty AMM might be the culprit.) I looked through the www.swedishbricks.net board and discovered that there are several dozen potential problems that could exhibit these symptoms.
Can anyone help me to narrow them down? (Repairs are a strength but diagnosis is not.)
Thanks.
