Actually the truth of the matter is I had an Explorer before the Colorado. That had disc brakes all the way around. I thought the drums in the back on the Colorado were a little bit bush league and the lack of stopping power was noticable, but I just got used to driving it that way. The brakes were the first problem I had with the truck though. The truck was ... Read More

Yes, snaproll1, you are somewhat correct in that there is an area in vehicle computers that is called "volatile ram". This area stores the engine or body code used to help troubleshoot problems. This area is also used to store data used in "learning curves" for engines especially. For instance, the engine computer stores data it uses to know how much "fuel trim" is needed for a particular vehicle. It learns ... Read More

I completely agree with Den052. While the battery going south may have initiated the problem, replacing it won't fix it. The low voltage of the old battery pushed a lot more current through the connectors then they were designed for - this includes the fuse connectors in the fuse block, causing them to overheat and lose their gripping. This results in an intermittant connection that can fluctuate when outside temperatures rise ... Read More
