Ok ...when i first start my car and drive it it runs fine...but if i get on it(or long drives) after a min or so the check eng light comes on and it starts to spuder (sounds like its missing) but when i turn the heat on after a min it stops.first i thought it was the thurmastat..so i took that out and it still does it...and it seems like its hotter then norm and the motor has that ping noise when metal gets to hot..so is it the water pump or is it the cat making it run hot..I know it sounds more like the pump but i just want to be sure before i put one on...

 

ok never mind i found out what it is..i took a look at the oil and there is water in it, so the head gaskit is blown!! does anyone know of a good head gaskit..never had to get one for a honda.
