check engine light

Hello, all. Recently bought a '98 328IS with 86,000 miles. Already had to replace the t'stat and coolant temp sensor. Now I have a CEL and AutoZone says it reads a possible vacuum leak, bad cats, or bad valve seal letting nasties into the exhaust flow. Can't determine if fuel economy is down, its the same as when I bought it here in Central Ohio a few months ago. It runs great and is a really fun car. No idle issues. I do hear that hot tick-tick sound after the car is turned off, but don't know if that is a bad cat or symptomatic of a problem upstream. Anyone out there with a similar experience? I'm getting tired of having a CEL for all but 6 weeks of ownership and will have to look at a Lexus IS if this keeps up. Thanks.

what they need to do is clear the codes and see what code actually is the root problem.. .when one code goes off, normally it creates a chain reaction of faults (most are dummies that are related to the initial problem) once they clear the other codes they can at least go after the proper code.

Buy a code reader...

Yeah buy yourself a code reader so you can read the codes yourself. I like the Actron 9135, its easy to use and made in the USA. Its usually something simple that causes a chain reaction of codes.




Actron Website


You can find them on Ebay or just about any autoparts store.
