Carry on reconnecting the electrical connectors and the negative battery cable while inspecting for 'leaks with the ignition on for some time. When replacing fuel injectors pay attention to the original part number, disconnect the connectors, and remove the injectors while saving on gasket. Check the filters for contamination and if needed change them with new ones, make sure to lubricate the O-rings before fitting them. The TPS should not be cleaned with solvents and should be installed back after removal while in the case of IAC valve, a new valve should be installed with paying attention to the size of the pintle. The fuel meter body assembly is reused with new gaskets and once again the fuel injectors can be removed and a new set of gaskets and O-rings can be fitted after cleaning the throttle body assembly. With regard to electrical systems, make certain that all electrical connectors are mated securely, check accelerator pedal functionality, and look for leaks before completion of the air cleaner housing assembly and its affiliates.
