i was thinking to add a small resistor to the oxygen sensor thus making the coputer richen up the fuel mixture. i know that the ideal is 14.7:1 but the mixture for best power is a little bit richer. i was just wondering if this will work. i think that i am gonna try this if i can still find my old 02's lying around

do search for the resistor mod..... many people here that know say its crap.. i agree... it would have worked on older cars, but today's computers know better.....

i think that is for increased timing bu fooling the iat

The IAT resistor mod and O2 resistor mod are essentially the same.

Don't do it.

If thats the case, I agree, I put a resistor in my IAT sensor on my blazer and I acutally believe it made it run worse, DEF NO improvement. but different beast may get different results.

I would not mess with it. Lean is clean, if you have emissions testing your readings will go up, richer is worse for a car, foul plugs, kill the cat(s), kill the O2, etc
