i have a 89 civic si...out of no were its just not running right.....wen i step on the gas it wants to die...i have to step on it really lightly to gradually get the rpms up but even then it runs weird....slow....almost feels like the fuel filter is like cloged or something...or maybe it has to do with the throttle...i dunno...help..and also...i changed the oil on it and all the sudden i check the stick and its like under the first dot....i put 2 quarts in it and check it and its still empty....there is never any oil anywere on the ground so were is it going?
