a few days ago i adjusted the valves, and changed the , thermostat, cap, rotor, wires, fuel filter, and the car seems to be getting no so good of gas mileage. i topped off the gas tank til gas was pouring out and now its at half tank and the trip meter is at about 127 miles. the performance of the car is seemingly perfect. the only thing other than the bad gas mileage is somtimes when the car is just about all the way warmed up if i rev it up a little when the revs drop it goes like 2-300 rpm under where idle is supposed to be for a second or two then raises back up. the only thing i didnt get to do is set the timing because i dont have a light, and i am getting that done tomorrow. what do you think i should look into? :thumbup:
