my 1996 cadillac was leaking the antifreeze and the coolant temp. was 255 so then we took it to pepboys and they supposedly fixed it... so wen i tried to leave and start the car it was struggling like it wanted 2 start but it didnt the first 2 times then it did...it keeps doing it and i wanna know if anyone knows the problem?

 

well first of all you have a 96 which had a lot of problems with head gaskets and head bolts pulling out of the block, You may have damage to the engine. Without seeing it for myslef its hard to say...but if it overheated it would not suprise me if you have a dmaged engine.
