whetstonewestie Posted May 15, 2007 Author Share Posted May 15, 2007 is all completely from westfield. 1600 modular build supplied from WF with sigma Zetec engine and webcom alpha ECU. Mark mentioned testing the voltage of the Throttle Position Sensor and then if it is incorrect undoing the screws and adjusting it. have not had the chance to try this yet Quote Link to comment Share on other sites More sharing options...
perksy Posted May 15, 2007 Share Posted May 15, 2007 Check TPS as Mark has suggested If it's been incorrectly set you will have too high an engine idle speed Voltage should be in the Alpha instructions... Quote Link to comment Share on other sites More sharing options...
