Cleaned the maf and throttle body, made sure there was a rag on the opening so any runoff didn't get on any parts, and did a coolant flush also, all in one day and now car will not turn over, as in I'll do it and all I get is click, and nothing and then if I flutter the key back and forth it may start, sometimes it'll start right up, sometimes it won't, idk what I had done but I just cleaned the throttle body the same way he did. Any ideas as to what the deal is?and today at lunch I did it and it would start and hesitate and I'd try to give it a little gas but it would do nothing and slowly due regardles??? Help it's my daily :/

Which car, model and engine is this happening on?
