Known issues on the 1998 Eldorado. One recall is on federal record for this model year, covering a misrouted canister purge evaporative emissions harness: the harness could interfere with the cruise control and throttle linkage, preventing the throttle from returning to closed. Owners have filed 56 complaints for the year. The factory diagnostic and repair procedure for that harness routing, along with every other system on the car, is here.

Whether you're rerouting the evaporative emissions harness, chasing a cruise control fault, or working through a scheduled service on your 4.6L V8, it keeps you on the OEM procedure and the correct specification for your specific 1998 Eldorado.
