Re: Engine Dies when in 4-wheel drive

Only thing I can think of is that the extra load of the tranfer being engaged is dropping the engine RPM?? I had similar issues with AC coming on, but idle would be to high when it was not running. Solved it using smog fast idle solenoid off of a Qjet I had laying around. Wired it to come on when AC compressor engages, you could do the same to the 4wd indicator switch on the transfer.
