What's the exhaust smell like? Any eye-searing fumes? Black smoke?

How long did you drive it for?

And get the code read. AutoZone, PartSource and many other places will read the code for you for free.

Did the gas come from a name-brand station with high traffic volume?

Yes,gas stations have had diesel put into their gasoline underground tanks by mistake,and water in the gas is another problem. Shell(IIRC) in Orlando sold bad gas that required replacement of fuel pumps.

I had the same problem with a 2001 LX. Pull the spark plug cables one at a time and inspect for oil both inside the plug and down on the spark plug. I had a leaking valve cover gasket and the oil was preventing my #1 cylinder from getting any spark whatsoever. It would be alright at idle, but would buck like a sonuvabitch when the engine was under load. If this isn't the problem, then stick with the free "Autozone Diagnostic" but take whatever they tell you the code means with a grain of salt. Some of these kids aren't the brightest.

I was surprised to find out how serious it is to run diesel in an injected gasoline engine. In the Yahoo Prius forum somebody who got diesel in the tank and ran it until it stopped bent a rod! I thought there must be a mistake until another member related the same tale of woe. Then it dawned on me that the diesel doesn't burn or vaporize, it just builds up until the cylinder hydraulic locks :-( :-(

BTW - I agree it sounds like bad gas, and the car should not be driven until the problem is resolved. But on a related note... has the timing belt been changed?
