I diagnose my ignition coil to be faulty, by ...

Hello, to answer your question. Yes, a faulty ignition coil will cause a 'check engine' light to come on. However, it may be represented as a misfire code as well. What you explained should have taken care of the check engine light. Also, what kind of gas do you use? Check with your owners manual and use the recommended gas rating or better. Hope this helps. Feel free to reply with any questions.

Relist: I still need help.
The response to the question is good. But I sent this question about an oil leak twice and no response.

My 1995 volvo 850 has an engine oil leak on the driver side. I've search for it by flash light, checking the camshaft/distributor/oil sump/transmission. It is definitely engine oil.

I now used 10w40 which has slowed the leak down.Any suggestions.

Thanks Chris.

Hello, try checking your valve cover gaskets. They tend to leak on most cars over time. Sometimes its easier to see a leaking valve cover from underneath the car (meaning on a lift not actually crawling underneath) Worst case scenario, a possible leaking head gasket may be the culprit but not sure exactly how your engine is set up so I recommend starting with valve covers. If it is the valve cover gaskets that are leaking, the part itself is only about $30-40 bucks each (v6, v8 need 2). Its the labor that can be expensive. Depending on the design of the particular engine, labor costs vary (i.e the more parts that need to be removed to acess the valve covers, the more labor). If you're able to do them yourself, be careful when handling rubber breather hoses and vacuum lines. After a while, they tend to dry out and become brittle. Use care to reduce the chances of breaking them. Hope this helps and let me know what you find.
