Running really rich search was useless.
 

I've been searching for 2 days straight 3-4 hours a day for how to adjust the air fuel mixture. I have tried everything you guys have said to no avail.... My car is running so rich it can make your eyes water. I was on the interstate the other day and a friend of mine a mile or so back called me and asked if i was on I-840 cause he thought he could smell my car!!! I was on the interstate....it's rediculous. can someone point me to a full air fuel adjustment webpage? Thanks my mpg is around 5mpg right now....

there is no air/fuel adjustment for a stock FC. Only for idle. Once your off idle, your ECU takes over.

Change your 02 sensor, and scan your ecu for codes. Possible you have a bad sensor somewhere.

Most likely it's definately your O2 sensor... Mine was bad and good lord, i had hooooribble mileage - 170 miles in one tank! Id check it, you could go take it by a shop that has a meter you hook up to read the o2 sensor and it will map out a whole thing that shows what it's doing.

yeah 176miles to a full tank. i'm gonna change the o2 sensor tommorrow.. $42 not too bad..

where did you find a new o2 for 42 dollars?!!??!

i had to get a crappy autozone universal o2 sensor, and i dont even think it works right.. I had to cut and splice to plug it up, and i have a RB header that has an extension wire... People say that you cant cut the wire of an o2, because it changes the resistance or something and makes it read differently.

hey i live in brentwood... frankline eh?? where at??

89 GTUS (bigger tank)... but i used to get 250 on bone-dry... then i took my cone filter off to stock, now i get 275 when the light comes on!!! WEIRD!!! need to change my O2 also

Autozone......got the Bosch one that is made for our cars, NOT the universal one........ for $36! AND it is a direct plug-and-go installation

i guess they didnt have it in stock or something when i went... ohhhh well, i guess i should get my engine back into my car before i worry about gas mileage.. hehe


Justin

I live in Cool Springs right down the road from the mall.. I'll let you guyss know how the o2 works out.. still trying to time the car right....
