I have a '90 V8 that runs perfectly & has new parts: plugs, wires, distributor caps, rotors. However, when cold, it takes about 15 seconds to start. What might that be? Many thanks, Tom

Its probably leaky injectors (ohh no not that!! Big $$ ), or maybe a fuel regulator...(easy and in expensive) but you should try by searching the audifansdotcom archives.. first try the google box on the main page then go into the mail lists click archives then v8 then search by month and thread... you should find a load of info not available here... sign up for the list if you really want to have fun ...
