could replacing the IAT sensor with a resistor make the engine run rich? if so, how bad is it?

i measured the IAT's resistance mid-day (farely warm) on a cold engine and it registered ~5.8 kOhms. i don't know how much this resistance would go down relative to the increase in temp, anyone have a chart or even a rough idea? the 4.7 kOhm resistor "mod" wouldn't make much sense if the IAT doesn't dip that low in resistance...

 

its gonna add fuel to your car when your car dosent need more fuel.. why bother... it will cause worse gas mialage, and screw up your cat if you have one

 

IAT sensor barely does any changes to your tune, Ive ran without one for a long time in teh past, and done this on other cars as well. Most Ive seen it do is take of a degree of timing here or there thats all.

 

well not nessesarily. the main reason I'm even asking is because I want to make the car more drivable at lower speeds. see what happens is there's a gap or delay right off idle where the engine seems to go dead for a second and then comes back to life. my theory is the fuel delivery off idle is screwed up and I'm trying to find the cheapest way to fix it without causing damage. so if the IAT mod adds a little extra zing off idle, I'd be more than happy. but if it also causes a much degraded gas milage and a gunked up cat, maybe I don't want it?

Tiago - I'd thought different, with all the people posting about their cars running like **** after IAT failure. but, perhaps that was mitigated by some other problem...

bottom line, I just don't want to fubar my car.
