i topped my anti freeze up yesterday and ever since my car is misfiring on tickover.when i first start it it revs at 1500 with no misfire??anyone have any clue whats wrong with it?

 

can anyone help?

 

Silly things first ... did you spill any over the sides of the engine... may cause a short / earth out a plug lead?

Did you disturb any other hoses that may now have an air leak?
Does sound a bit like the idle control solonoid,


dunno if that helps
