    Had silly issues with my fuel injectors and fuel leak at the fuel rail. Fixed it all, now it starts clean for 2 seconds before shutting down. Off to my new issue - I'm getting P0121 and P0123 - throttle position switch circuit high and circuit range. Ugg - so close - I'm stir crazy and want this thing moving again!

    As always, any help is greatly appreciated!

    End to my saga - the throttle errors were cause I disconnected a connector that runs to through the fuel injector harness - it all seems to work now
