Question about 2001 Mercury Cougar
My check engine light has been on for a while egr valve problem.This morning I went to crank my car and it idle very ruff only in park and idle if you hit the gas it smoothes out.
Your EGR valve shouldn't open up during idle or the engine will run rough and may even stall. Remove it and clean the plunger and port with a wire brush and some carb cleaner. Test the diaphragm with a vacuum pump. If it doesn't work after cleaning, or the diaphragm is bad, buy a new EGR valve.
