Re: 2001 taurus sel duratec rough idle?
2000 and newer Duratecs didn't have IMRC. Just regular runners. Definetely check the MAF sensor and clean if necessary. There is a specific cleaner for MAF sensors. Also check to see if the throttle body is dirty. If dirty, remove it, remove the TPS and IAC valve, and clean it with carb clean. Make sure you clean the IAC passages on the TB. An OLD toothbrush comes in handy to scrub the bore and TV. IAC is a little hard to clean, just make sure you hold the solenoid end up when cleaning, and allow to try before reinstalling. After re-assembly, disconnect the battery for 10 minutes. this will clear the adaptive memory. Reconnect the battery, start the engine, allow it to idle a few minutes, then take it for a drive around town, and on the highway. This will get the adaptives to start reseting. You should see a difference now in how it runs.
