Rough idle when hot
My 2000 C5 has a rough idle when it's hot(Engine). It runs great and smooth. But lately I've noticed a miss when idling. Then when I take off under normal acceleration I get a hesitation. It smooths out and runs great at cruising speeds. I think it feels like maybe a fouled spark plug or injection problem. Sometimes when I'm stopped i'll put it into neutral but it gets no better. You can here the miss in the exhaust sound. Where should I look first? It has 49K miles and as far as I know it's the original plugs,wires etc..etc..
ANy help would be appreciated.
