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.
