hey all (clio problems)

hi there i hava a clio 1.4 16v W reg, i have had endless problems with this car first was PAS Pump then speedo sensor went then the dog bone for gear stick went and the rocker gasket has been done. Anyways all of those issues are sorted now the damn thing is missfireing i have tried the obvious like ( coil pack, fuel injectors, fuel rail, spark plugs, had a friend do and earth to check for any brakes in wires, cleaned off the cam shaft sensor and maf sensor.)
but its all well and good trying all of these things but i am spending so much money trying to sort this issue and its still not sorted. i do have a friend pluging his computer in to it today to see if he can find anything. Renault forums you are my last hope. thanks

	MAF MAF A mass airflow sensor is used to determine the mass of air entering the engine. The air mass information is necessary to calculate and deliver the correct fuel mass to the engine. Air is a gas, and its density changes as it expands and contracts with temperature and pressure. In automotive applications, air density varies with the vehicle's operating environment, and is an ideal application for a mass sensor. (See stoichiometric, ideal gas law, and density.) There are two common types of mass airflow sensors in usage on gasoline engines. They are the vane meter and the hot wire. Neither design employs technology that measures air mass directly. However, with an additional sensor or two, the engine's air mass flow rate can be accurately determined. Both approaches are used almost exclusively on gasoline burning, EFI (electronic fuel injection) engines. Both sensor designs output a 0 - 5.0 volt signal that is proportional to the air mass flow rate, and both sensors have an IAT sensor (intake air temperature) incorporated into their housings. When a MAF is used in conjunction with an exhaust gas oxygen sensor, the engine's air/fuel ratio can be controlled very accurately. The MAF sensor provides the open-loop predicted air flow information (the measured air flow) to the engine's ECU, and the EGO sensor provides closed-loop feedback in order to make minor corrections to the predicted air mass.
