my car sputters once it warms up making a puh puh puh puh noise. anyone know what this could be? this only happens at idle. it all happened after i misshifted and overrevved it. could this be my valves?

you might do a compression check, or, while the car is idling, pull the plug wires one by one to see if any cylinder sounds weaker than the others. I don't think it's a good idea to run around with bent valves if that's your problem...

i found out i need my valves adjusted. ill be getting it adjusted later tonight, if its adjusted will the sputtering go away? also, now my idle is starting to get really low, like around 400-500rpms. anyone know what that could be?
