iat sensor question
I have a 2003 Chrysler t&c with the 3.8. I recently read somewhere else about unplugging the iat and putting a resistor in instead, the theory behind it made sense so I tried it. I put a 5.6k in. the check engine light came on and after about 35 miles the light went off. Initially I thought I was getting better mileage based on my factory overhead mileage avg reading, but I wasnt sure so I took out the resistor and plugged the iat sensor back in. Now my check engine light came on and hasnt turned off. Should I be concerned, should I put the resistor back in? any ideas?
