Could bad valves cause misfire at idle?

[JMiller]

Im thinking about buying a car off ebay but it says in the description that the car misfires at idle . Heres a link (http://cgi.ebay.com/ebaymotors/ws/e...EWA:PIC&viewitem=&item=110145172769&rd=1&rd=1) Ive read alot of post about misfires and bad idle but i was wondering if bad valves could be the problem. the car is a 97 Eclipse GST bored 40 over. Any help would be great. thanks in advance.

They can, as can bad lifters, low compression, bad rings, dead/flaky fuel injectors, worn-out spark plugs/wires... there's a lot of things that can cause idle misfires.

Misfires at idle. Does it smoke...color? There are so many things that could cause a misfire. It goes from simple (wires or plugs) to valve seals, valves, lifters, etc. Be careful. I'll never buy anything unless I can drive it first no matter how good of a deal it seems.
