Make sure you check the throttle sensor at the throttle body. Should hear a click just before it fully closed. Check it resistance while moving the throttle. Resistance should sweep while opening. Any dead spots means it worn through the contact area. Another is the NTC seƱor for your engine temp. This has all to do with enriching the cold star. Sometime this sensor fails and leaves you with high fuel consumption and bad driveability.. Check ignition rotor for 1k Ohm. Check also the fuel pressure regulator. Should not have any gasoline in the vacuum hose side. Just remembering the basic checks I do when trouble shooting.
