2002 Crown Vic, 230k miles, No power/Slow acceleration??
So I bought a 2002 Crown Victoria 4.6L off auction, it had 230k miles. But when I drive it, it doesn't feel like a v8 at all, feels like a 4 cyclinder running on 2 cylinders, it has like very little power at all, and it is very slow to accelerate. The thing is though ,I got it smogged and the guy said the engine is in great condition and it passed all the tests good. I tried linking up the OBDII scanner to see whats up but surprisingly there weren't any codes. So I changed the spark plugs as well, but that didn't help either.
Any ideas? Thanks.
