please help me

A little while back my car over heated and I had to replace the radiator because it had a hole in it. Well ever since my car has been really boggy. It'll drive fine for about five minutes, then it starts to bog, almost like its misfiring. I'm thinking maybe i fried a spark plug when it over heated, but what do you guys think, and what should i do? it feels like it has a total loss of power, i had the compression tested and its fine, also no smoke or anything is coming outta the exhaust. but when it does start to bog it sorta smells a little rich. any help is appreciated, thanks.

Is it over heating again? cuz thats what it sounds like. It doesn't sound like a spark plug to me.

naw, its not overheating.

you probably destored some internals and burnt some bearings when you over heated the engine.

Do you hear any unusual sound when the engine is running?

u might wanna check and make sure u didnt warp anything (head, block, gaskets) i dont know what parts of ur engine are alluminum, but i do know that when alluminum engines overheat, they sometimes warp (i gotta swap out the engine in my 84 prelude cuz it overheated). also u might wanna check the intake manifold and its gaskets, if ur smelling gas.
