This might be a little fluffy question, but my engine is just weak. It runs fine and temperature and oil pressure are all fine, but it feels like 50 of the 180 horses have gone to the slaughter house and turned into glue.

What can I do??? The car is from 1990, but coming to think of it, it performs only slightly sharper than my old 300 tdt of 1985...

(It drinks gas like all the horses were awake, though...)
