Re: Diagnostic Test Code Definitions
The throttle position sensor and EGR sensors are both connected to your throttle body. Remove the EGR equipment that bolts to (the front of) the EGR spacer (between the throttle body and upper intake [does not require that you remove TB or intake or even air filter assembly]) and clean it out really well with some carb cleaner or something, but be sure to blast it out REALLY well with water, since the residue of carb and brake cleaner can eat at the rubber diaphragm inside the assembly. EGR equipment rarely goes out- it's typically a matter of things clogging up.
Get some electronics cleaner and blast the Hell out of both sensors and both sides of the connectors on both senders.
If you're still having trouble, try replacing the sensors, as they could be fouled.
Run lots of fuel system treatment in your fuel tank if you're still having lean bank issues after you do all that.
