I have a 90 Rex Si. I have the B16A. I get the worst gas miliage. I get about 181 miles to a FULL TANK OF GAS? Any ideas?

 

Tune up, spark plugs, 02 Sensors, oil change, new air filter, etc... also run fuel system cleaner

 

how bigga rims you got? big rims will kill it. stop and go....................

 

I changed my fuel filter on my 91 crx si, and then it started getting crappy gas mileage. Like 25mpg compared to 31. I looked around, and noticed i forgot to connect the line back up that goes into the charcoal canister thing. Check yours and be sure the lines are connected up to it properly. The one that was disconnected on mine was the one that comes out of the bottom of it(canister) and into the frame. Very easy to overlook and leave disconnected if you have removed it for any reason. This is just one of the many things that can cause crappy gas mileage.

 

I have 17" on my Rex. I put new Bosch+4 in it. I heard that they were bad for honda-acura engines.

 

German plugs in a Japanese engine = :a:

 

Put 15's on ur rex, and trash those 17's, u will get hella better gas mileage.

 

17's are just nasty
