try your egr valve its a pain to replace but i just had to do it. A few weeks ago i was having bad gas milage i cleaned my throttle body worked better bus was not all there. Now i replaced the egr valve and its like new agin..( 96 corolla 1.8)
ok so i took a bunch of stuff out of my trunk mostly tool's. i still have my sub and amp installed. i cleaned my egr valve and seem's to help a lil i notice better gas milage and some more power. when removing my airfilter tube from my throttle body there was this black stuff almost looked like...
is there anything we can do that will help us get better gas milage that you know of?? i have a 96 with a 1.8 and i'm only getting 300 miles to a full tank.
