Yesterday the Emission System Warning Light came on in my Ford Windstar. I did some reading on the subject in the owners manual and on this site. It sounds like it could be a number of things that could cause it from the pcv valve to the cat. Converter. I did notice the van idling rougher than usual yesterday so the first thing we will try will be the pcv valve, then the EGR valve.
Does that sound like a good approach?
Is the van safe to drive until we figure this out?
Also, I've read that the warning light won't go off when fixed so how are we to know if that was the problem or not? A few months ago, I got a warning light for brake fluid. We added brake fluid and the light went out and hasn't come on since. Maybe that will happen here also?
Thanks and I look forward to your response.
have the same problem?
