One. I have a 96 Chevy Blazer with 91,000 miles on it. 4.3 V6. It has something that is making the battery drain after I turn it off. I can let the truck sit over night, and it barly starts, or just clicks. I bought a new Interstate battery. Still the same thing. I checked for lights on in the glove box, and under the hood. I brought the battery back and had it checked for a load. The battery is fine.. Will one of those testers that plugs into the computer tell me what might be on to cause that drain??, or how do I find whatever is draining.. I wouldn't think it all could be drained down from just the radio memory..

Two. A Lady where I work has a 2010 Toyota Tacoma. It was getting 23mpg. Now it seems weekly to go down to 21mpg, and her lowest has been 18mpg. She went to her dealer. He said that the injectors needed cleaning.. She already did that, but that didn't help.. Any thoughts on this as well?? Thanks.. Al
