my name is cody, im from muscle shoals AL, i bought a 1990 honda accord cb7/f22a1/h2a5 5 speed a couple years ago for $250 and and old set of ford heads, i put a distributor on it and have been driving it ever since. i started wondering about gas mileage a few months ago so i came up with a few idea's, this is what Ive done to it since then, btw the before mpg was 26 city 28.8 hwy
removed the p/s belt
bought a new IAT sensor and mounter it to the exhaust side of the head
replaced every single sensor under the hood
new fuel pump/filter/regulator(this was a have-to situation probly not nessecary for mpg)
platinum plugs, 8mm wires, advanced timing to the max on the slider
polished the throttle body, ran a new intake hose across the front of the car(near the exhaust)
got it aligned
removed unnecessary weight
my city mpg is still not certain cause i only use this car on a 100 mile round trip with only 3 stops along the way but after doing the sensible stuff I've found on this site combined with my own experiments Ive driven 59.3 miles on 1.21 gallons.... that's 49 mpg yall!!! hehehehehe
