I just bought a 4.2L LTZ a week ago and it had been sitting for an unknown amount of time. Initially I was getting 18.4 L/100KM but each day it drops a bit and now, after a week, its at about 16.2 L/100 KM and appears to still be slowly dropping.
The vehicle did have work done on it which I assume meant disconnecting the battery and losing the control module memory. Could the initial high consumption and slow improvement simply be a case of the control's re-learning?
I immediately installed a new air filter. The old one was only slightly gray but the pleats were all wavy which means they'd been wet (probably condensation) and the paper was probably mudded and plugged. I have a set of iridiam plugs ready (the 0.50 gap for the 2003, not the 0.43 for the later models) but I've been waiting to see if the consumption will drop to around 13L/KM I think I should be getting (15KM city, 10KM highway - twice a day!) and a light foot.
Should I just pull the trigger on new plugs (127K kilometers on the odometer) or wait for the consumption to drop more? Anything else in the realm of simple fixes for a vehicle that's been sitting for up to six months?
I have thought of the gas being skunky but there was only 1/8th tank when I got it and I filled it immedietly so it shouldn't affect consumption very much.
Just lovin' this truck!
