Hello my 97 idles poorly on first start up on cold mornings. Cold is around 25 -30 F. It always starts fine but has a hard miss for a minute or 2 until it warms up a little. I can still drive it. It does this in summer as well but not nearly as noticable. I changed the spark plugs last summer. I have not looked at the vacuum hoses connected to the injectors or cleaned the intake "adjuster unit".

Any thoughts where to start looking?

Also I get a fuel smell in the cabin when the tank is full. This has been a problem since I bought the car this summer. I changed the 2 big Orings on the fuel tank sender and fuel level. Could this be related? Maybe small fuel leak bleeds down pressure?

Thanks in advance. Bill
