Question about 2002 Mercury Sable
IT'S THE TIMING CHAIN/BELT! Well at least that would be my diagnosis based on previous experiences. Read On Below.....
I had this issue on a 2001 Ford Escort ZX2. I lost all my uphill pull & had to gear down on hills that I normally did not. I took it to a mechanic buddy & he determined it to be the timing chain/belt. When he tore it down he discovered that it was not the actual chain but was the chain's tensioner pully. It was in more than a few pieces. I had him replace the chain as well just because it was probably the OEM part & I didn't want to have to go back in there to replace something that he had to take off to replace the pully that was bad & I had already bought it so it was a no brainer. So it could be the timing chain & if by chance it is you SHOULDN'T BE DRIVING IT AT ALL because it can & will eventually, in a nutshell, cause damage to the point that the engine would be inoperable altogether. I was lucky that I didn't screw up the engine on my escort.

You will need to do a compression test on the pistons. it could be the stem seals have failed on the valve stems. (this is for hills) racing /roaring, racing could be a weak clutch if manual/ auto can be incorrect settings been put on gear box. roaring can be a leaking manifold or leaking exhaust before or after first box or cat leaking.

thats when you need to get it scanned sounds like water is getting in a sencer o2 perhapes but scan it for the code it should be stored in the memory

SOURCE: "check engine light flashing"
The flashing check engine light is typical of a misfire issue. There are two things I would do to start with.
1. Take the vehicle to an auto parts store like Autozone and have them hook up their scan tool so that they can retrieve stored trouble codes. Even if the check engine light is not on, they should be able to retrieve recently stored codes.
2. Do a complete tune up. New plugs, new plug wires, new air filter, new fuel filter if it has not been done recently.
If the parts store pulls the codes and they cannot tell you what they mean, post them up here and I will see what I can dig up for you.
