Question -
Starts and idles fine. But after a couple of minutes there is no power under any load condition (when going uphill or starting at red light). Motor acts like it's missing fire; entire car vibrates. Have been to four garages and they have done complete "tuneups", cleaned the fuel injectors, new plugs and wires, etc. but the problem persists. Have spent over $500 so far with no results. Does not burn oil. Fuel gauge hasn't worked for years! "Miles per gallon" indicator on dash shows very low (7-10 mpg, even downhill))when engine is acting this way; but when engine is acting ok, shows normal readings (40 mpg downhill; 13 mpg when on level). Beautiful car; 106,000 miles.

Lets check your computers for CODES:


1. Ignition ON. Engine OFF.

2. Simultaneously push and hold the OFF and WARMER buttons until the whole display illuminates and then release the buttons.

3. CODES will start to appear and will stop at .7.0

4. Write down all the codes EXACTLY as they appear on the display and tell me what they are.

5. turn OFF ignition.
