My car keep thuding/studdering when you apply gas to it after you drive it for awhile. Once it starts the studering, it also makes a pop sound under the car (not in the rear) and when it studders and i apply gas i can put my foot all the way down and it wont go then it would start studdering and go for a bit and then studders and loses speed. Originally there was a leak int he head gasket into one of the spark plugs but i used a Head Gasket Sealer to stop it which it did but the studering was starting when it was getting water in the spark plug. I flushed out the entire system several times and for hours and no change. At times it would just die with out warning but only when i was going slow never when i was going past 20. When i had it in neutral it idle all right but once i put it drive it would studder and die. The spark plugs are still good. Suggestions ideas?

Based on the symptoms that you described I would recommend biting the bullet and replacing the head gaskets. Head Gasket Sealer is a temporary remedy at best so the leaking will undoubtedly persist unless you resolve the issue at its source.

Additionally, although the spark plugs may still be in good condition that does not necessarily dictate that your plug wires are still in decent condition. Since wires are relatively cheap I would advise just replacing them and seeing if that resolves the issue. If that doesn't help alleviate the studdering issue then I would examine the actual ignition coil.
