Service 4wd System message
I have a ghost "service 4wd system" trolling me these past two weeks. when it comes on the RPMs drop to zero and comes back along with dash lights and chimes. then MIL. then tranny sticks to 8th. MIL goes away after parking overnight. I've been to the dealer twice and 1st time theu caught a bad cam sensor. 2nd time no stored codes so they reflashed PCM and TCM.
I'm going to stay with OE PCM for now. Seriously don't think these things are worth $28k buyout at end of lease in 9 months.
