That is a missfire code and from what you said you have done that should have taken care of the problem. Mind boggling......

well that dealer is retarded. ill bet its ur o2's. changing the head gasket is a little drastic for a misfire. a lot of misfires r due to bad o2's. also is this always around the same speed? if so check ur TPS it may be worn down and not making a good connection.

O2 Is an oxygen sensor. it keeps track of how much oxygen is in ur exhaust and is a leading factor on how much fuel to give. if this is wrong u may be dumping too much fuel or not enough causing an improper spark. u have 4 oxygen sensors and theyre not that expensive. a TPS is a Throttle Position Sensor and it detects how much throttle ur giving the engine. but like i said if it does it at a certain speed, it might be a TPS. the TPS is located on the driver side of the throttle body and is a 3 wire sensor.

do you have a K&N filter? if so, find another car and try the M***AirFlow(also called MAF) sensor from it. it may be contaminated with filter oil. and how did you clean your injectors?
