ok we own a 1989 buick leasaber custom. it runs like a top. how ever. just today the check engine light has come on. now it does not stay on. when you start down the road its off then when you stop it comes on. then when you go again it turns off. i have plans to check the air filter. but any other ideas? its not blinking and i have no obd1 reader and idk how to check the code
Some have variations of a cold air intake. Many will have intakes that are extended in places like the fender well to draw more outside air into the engine. Regardless of what these manufacturers of cold air intakes claim, I would not expect much in terms of horsepower and gas mileage from installing one.
No stock vehicles do not have a cold air intake, not usually. Some expensive sports cars do. They are good, especially in the places that are extremely hot like Arizona. That is the real question you need to ask is will it be worth it based on the climate where I live? The benefit to cold air induction is that the cold air combined with fuel getting sprayed on to hot metal makes for an efficient burn when the cylinder fires off. The colder the air, the better the fuel becomes a gas, the more efficient the car is. Here it is, if it is hot for a while in the summer it will help when it is hot. If you live in Michigan I would not recommend it. If you live in CA, FL GA, AL, LA, or anywhere in the desert it would probably be worth it in the summer, but don't go taking it off in the winter.
Most all auto parts stores have stopped reading the OBD1 codes but here are instructions to check it yourself. www.extreme-check-engine-light-co.
something hooked as much as the flexibility administration module can turn on the verify engine gentle. and there's a protracted record of them. so which you will could take it and get the codes out of the PCM to work out what the undertaking is. and that i've got replaced alot of areas that autozone suggested have been undesirable and didnt restoration a undertaking. yet they're going to test it for loose.
A few auto parts stores offer a free scan to customers. It makes sense that they have a better chance of selling you a part if they can help you figure out what one you need. Check with Napa, Auto zone, Pep Boys, etc. There is a way to get the diagnostic codes out without a scanner. It involves jumping two terminals, turning the ignition to the 'on' position, and counting how many times the check engine light flashes. Then you look up the corresponding code. This can be found pretty easily by googling it, but I don't want to recommend that yet. If you can get it checked with a scanner for free, that way will tell you a lot more information. Edit: If you don't want to get the system checked with a scanner, then here is a link to how to extract the flash codes and what they mean: www.extreme-check-engine-light-co. Please remember that the code points you in the direction. You still should check the wiring, etc before changing the component. -Ken
