Alright i recently bought an 89 haonda prelude 2.0 S its having some serious running problems. when i bought the car i noticed that 95% of the vaccum lines were hooked up worng(some werent even conneceted) i hooked them up propreley, also changed all saprk plugs & fluids(besides transmission) and drained tank and filled it up full with mixture of carburetator cleaner and fresh gas. When i start it up and let it idle at about 750 rpm the muffler smells like its burning rich (and sounds like its missing)and if i kick it up to about 3000 rpm it starts spitting out this jet black smoke, if i make it idle at 1500 rpm evrything is fine. how can i fix this??? the tags on this car expired 2 years ago so its been sitting
