Ever get that "Service Engine Soon Light"? I've know people that drive around for miles with it on. I've even seen guys put a peice of tape over it so that it doesn't annoy them while they drive. They worry that because it's on it might cost them and arm and a leg to get it looked in to. And for obviouse reasons,it costs money to run a mechanics shop! One tool I have invested in that has saved me a lot of grief is a Autel MaxiScan. It scans OBD-II trouble codes. For those of you that don't really know what those are I'll give you a bit of a run down. Back in the mid 90's all the auto manufacturers decided a "universal" set of codes would be a great idea because mechanics and technicians had to spend a lot of money to have all the different types of scanning tools.
Now for those of us that just can't leave an endine alone and always end up "Hotrodding" damn near everything thing they touch this little tool might not do you any good. There is a set of parameters that stock modern stock engines operate with. When you start to put the go fast goodies then your in effect asking the motor to operate outside of those set parameters. I'll give you an example. I have a 96 Chevy truck that has a few modifications like aluminum heads and Flo-Tech Headers and various other go fast mods that mess with the operating parameters. In this case you'll need to get in touch with a place like Wester's Garage and have them custom make some programming for your ECM. And you'll notice that for the money,you're getting a smoking deal. Improved fuel economy,more power and overall you'll enjoy driving your car or truck a lot more.
