i have a 1992 honda accord mt 2.2l. It gets good gas mileage on highway but horrible in city. 30 mpg hw and about 17 in city. It use to get what it is suppose to get(22 to 25mpg in city). Spark plugs have been changed, air filter.
There has to be something that causes bad city but good highway gas mileage. Maybe a poor spark at higher rpm's while accelerating as to cause big ineffeciency in city cause there is alot of acceleration in city? I am just wildly guessing here.Does anyone know or can help?

 

Do you smell raw gas at all while driving ?

 

No i don't.

 

It all depends on how your driving behavior is in the city. If you are a manual driver like I am, I usually take it easy on the gas pedals when accelerating. (In other words, I'm not a lead foot, revving all the way to 4k every gear like some.) When travelling at one constant & consistent speed (like freeway driving), gas mileage tends to be better because the engine has to work LESS than it has to on the streets. But, when was the last time your fuel filter been changed?
