"Restricted Performance" message and rough idling

Yesterday is was sitting at a stop light and suddenly the engine began to rough idle. It doesn't stall, but the warning message simply indicates that there is restricted performance. I'm thinking that with 68k miles, it may simply be a clogged fuel filter. I purchased the car about a year ago and have had very little problems, but am not sure when the fuel filter was last replaced.

Does anyone have any thoughts?

    just got into my s type. message displaying restricted performance! running okay when message appeared. dare not go out in it now - what is the problem?

    I bought my 02 S type about 6 months ago. I haven't had any problems until 2 days ago when I stopped for petrol and noticed that the engine warning light had come on and there was a warning message saying "restricted performance". The car doesn't feel any different from the point of view of performance and there were no "idling" problems. When I stopped for petrol, the "mileage range" indicator read around 70 miles. Any ideas please ?

1993 Ford explorer.Began idling rough and surging


The test connector is in a holder at the back bottom of the fuse/relay box on the passenger side fender well. There are 2 parts to it: the main connector and the ground, you will need both connected to the diagnostic tool to get the codes.
Check your IAC (Idle Air Control) valve on the side of the intake. These get carbon fouled and tend to stick causing high rpm for extended times. Also the EGR valve should be checked (under the intake) as it will cause rough idle or stalling near idle.

Honda accord ex 2001 check engine light suddenly came on, car started to idle roughly


If it's running rough, chances are that it's misfiring. If the Check Engine light is flashing/blinking, it is definitely misfiring.
If that's the case, drive it as little as possible... Or straight to the mechanic because the more you drive it while it's misfiring, the higher the chance is of you ruining your catalytic converter.

Rough idle then stalls


Vacume leak or bad idle motor. With the car in park and running with the hood open listen for leaks moving your hand around the different hoses looking for a change in the sounds that you hear. The idel motor also makes the car idel up to 1500 RPM or so right at start-up then idel down, If it doesn;t the idel motor is likly. Check engine light is on when running? Test for codes, Follow code test charts don't skip any steps!.

Rough idle and engine light is on my 2003 aviator 4.6 engine


If there is an Auto Zone around your area, have the truck scanned for the DTC codes which is causing your idle problem. There are to many things that can cause your trucks idle to be rough. Once you have it scanned, we can address the issue and have your truck running 100% again. Auto Zone scan free of charge and can give you the step by step instructions to repairing and replacing the parts needed. Good luck and keep me posted, be glad to help.

2001 Jaguar XJ8 Idles rough while sitting


o2 sensors often cause a rough idle at stand still. Previously my xj8 had crank case ventilation (pvc valve essentially) issues that caused the check engine w/ restricted performance. I noticed a severe drop in gas mileage as well. Jaguar dealer fixed my problems in a few hours and it was surprisingly cheap. Its worth taking it to advanced or auto zone to see what the computer says. Then decide if you want to shell out for a dealer fix or if you can tackle it yourself. BTW, just to justify myself this is my third jaguar. I have a '94 xj6 with a chevy 350 inside it, previously owned a 95 XJ6 and currently have the xj8. They are wonderful cars if you can put up with their rough times.

Rough idling and poor fuel economy on 92ford f-150


This whole problem is most likey due to a sludged up intake and idle speed control valve, do the following procedure and it should take care of the problems, also run a couple of cans of LUCUS brand fuel injector cleaner through, I know u will see it is more expensive than other brands, but the thing is it works!
Here is the most common cause of surges and stalls at stops and low erratic idle speed and rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake
