Hope I'm not out in left field on this, but here it goes.
A friend was over this weekend and we got to talking about cars, as we always do. He was commenting on my Liberty & asked how I liked. In fact, I get asked this a lot.
Anyhow, I told him it was mixed, It is about the right size, the price was great, relatively easy to do basic maintenace on, etc. I told him I wasn't happy with the power being so high in the power band and the fuel economy. He was telling me that his dad bought a S10 4-5 years or so ago that didn't really seem to be running its best. So his dad unhooks the battery overnight, which apparently caused the electronics for the engine to loose what ever settings they had stored for regulating the engine. After a couple of dozen miles, the engine had relearned (for lack of a better word) or readjusted itself and ran better with more power & better fuel economy. Presumedly, the thing ran worse before because it was setup to run & pass emmisions from anywhere from High Altitude to sea level.
Assuming my friend isn't exagerating, has anyone tried this with their Liberty? Does the Chrsyler/Jeep engine management system operate in a similar way? How long would the battery need to be disconnected to allow any capacitors or memory storage to discharge.
I apologize for my lack of knowledge with modern engine management systems & terminology. My other vehicle is a 1970 Ford F100 with a 2V carb & a points type distributor. Very simple and easy to understand.
