Dirty fuel, dodgy or dirty plugs, a crook lead, dirty air cleaner, dirty throttle body, dirty IAC (also known as ISC), coil pack on the way out, dirty fuel filter. Firstly I'd clean the IAC/ISC. Easy and cheap to do. *Many idle issues are caused by this being dirty. Cleaning ISC Valve http://www.fordforums.com.au/showpos...9&postcount=43 Then I'd clean the Throttle body. This is for an I6 but the iside of the TB will look about the same as a V8. * As above. Cleaning Throttle Body http://www.fordforums.com.au/showpos...2&postcount=48 Then I'd check your air cleaner. Give it a bit of a tap and see how much rubbish comes out of it. Then I'd check your plugs. If you use the NGK $5 items, then replace the lot. Cheap and easy enough to do. If all that fails then you could reset the ECU. Resetting of AU ECU http://www.fordforums.com.au/showpos...9&postcount=85 If the problems still persists after resetting the ECU, then I'd get the leads tested and perhaps changed. If the problem still persists, change the fuel filter. Changing Fuel Filter http://www.fordforums.com.au/showpos...3&postcount=37 If all that fails, then take it to a trusted mechanic who can scan for fault codes. I'd be utterly surprised however, if you needed to after working down the list! LOL! All the best with it. GK
