okay my fuel milage REALY SUCKS bad,i have a 88 with renix, alot worse than it did before i did my motor swap to the 93 ho motor. 2 days ago i drove about 100 miles and it took close to 3/4 of a tank. this is rediculus. i can kind of afford it right now but soon as school starts and im not getting a pay check anymore is when im gonna run into the serious problems. its running very rich and i just replaced the 02 sensor about 200 miles ago, its also idling very rough too, which sounds alot like some of the the other threads said was there map sensor either broke or the line broke. so i just went out and looked to see if the line was broke and i realized im an idiot and dont realy know what in the world a map sensor looks like. but i knew the line was a small hard line that came off the throttle body. well i was in luck cause there is only one. it goes towards the back of the jeep to about the end of the intake manifold, then pulls to 90 degree angles then come back past the throttle body and to some small port/sensor looking thing build into top of the intake manifold. so im guessing this is my map sensor? sorry for being so dumb. so is there any test i can do to see if it is my map sensor? and if i need a new one about how much $$ should i plan on having to put down for one? once again im sorry for being such an idiot and all but hey at least i searched first and couldnt find much.
