I just had my clutch replaced today and my car started with the idling problem again. I changed the main relay when i got home and took my car for a spin. It was after dark so temp outside was cooler. Well my problem was not resolved as every time I came to a stop my car would drop down 500 rpms. Even when I gave it gas to get it back to normal rpms it would just go back down to 500 but would not die. It would shake pretty bad like it wanted to but wouldnt. Does it take some time for my ecu to adjust to the new main relay or am I looking at another problem. Car didnt run for 3 days before it got fixed(clutch burnt up while driving to New Orleans). Suggestions would be helpful..thanks
