Hello, New to the forums!
I have owned my jimmy for about a year and a half now, and finally decided to come on to the forums to share and read on everyones experience.
Lately its been having trouble starting cranks but wont turn over... I have done some searching so no need for help yet because I am going to check over the suggestions as fore mentioned already by a few posts.
Anyhow.. just a few things.. I was told that some of the vortec engines were good on gas and some not so lucky... True of False?
Second... Is there anyway to make this SUV better on fuel, ie:.. Reprogram chip?
Third, my friend told me that running the Auto 4WD is bad for the differential.. but manual says its safe to run even on dry pavement with 00 and up GMC's...
Any help greatly appreciated, thanks in advance!
