This is 88CRX. when I start engine in the morning, black smog continues for about 2 or 3 minutes and finishes when engine temperature is over 40, the car runs well all the day then. It would be grateful if you may have any suggestions!!

 

hmmm...how much smog are you getting out of there?
like huge clouds?!?

 

maybe you are burning oil. check your spark plugs and see if there is any oil on it. thats what i think.

 

Thanks for ur suggestion. the smog is not like clouds and it goes out when the engine gets hot enough, otherwise everything is not bad.

 

Thanks for ur suggestion! i try to remove the plugs but they r so tight that i can not do it myself, i may go to the service station. Many thanks!
