The terminals on this truck were disgusting. Unfortunately it did not improve the start time, still takes 2-3 seconds of cranking to start up, definitely not as quick as my Honda but I'm not very worried. I have a snarling suspicion that this the original 2006 battery!
Hey guys...9 out of 10 times it IS the throttlebody, when i first got my 04 screw, mine actually had to be replaced becuase it would stall at lights and run rough. Also, I am at 140k now and awhile back it caused a check engine light to come on and I cleaned it and it was pretty gunky, but after cleaning it, the truck runs fine! Hope this helps you out!
my 04 did the same thing it would stall out at idle. took it to my buddys shop when i was in mexico and we cleaned the throttle body and reset the computer and it hasnt done it since. but id change the fuel filter if you havnt i did mine my self and its not that bad.
