i've posted for this before about a week ago but did not get any responses and my problem is progressively getting worse and worse. About 2 months ago i noticed that when i start my car in the mornings it would struggle to stay on for about 5 seconds and then the idle would level out, shortly after that it would happen at random times during the day as well. Since lately it happens almost everytime i start the car and is taking longer and longer to level out. whenever i bring it to a shop it never does it at that time and they all say it has to do it so they can see before they check it. I should add that the car never stalls and the problem does not exist during driving or if i'm stopped at a light. I have already removed and cleaned my IACV and screwed my FITV......any ideas would help
