Here is the most common cause of surges and stalls and low idle 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.

2007 Lincoln Navigator idles hard when parked or stopped


What do you mean by would idle hard ? Don't you mean ruff or inconstant . Did it idle like that before the plugs were replaced ? If not maybe one of the plugs got cracked while being installed ! Take it back to who replaced the plugs an have them check it before you go chasing problems that aren't there.

2003 Ford Explorer XLT Wants To Stall At Low Idle,, especially when at a stop light


How does it idle in park , does it run ruff or smooth? Are any lights lit on the dash , check engine etc. ? Could have a partially plugged IAC air passage .idle air control (IAC) valve ! The engine computer uses the IAC to control idle , when under a load such as when put into gear the computer raises the idle ! It does this by allowing more air to by pass the closed throttle into the engine raising the idle ! If these air passages clog they restrict the air flow an cause a idle problem ! Now if it runs ruff at idle in park you could have vacuum leak ! Rough Idle How to Fix Ford Taurus Engine Stalls at Stop Signs

Obd light on, idle rough, smell, no throttle


The obd light with tell specifically what it is, is it gas or rotten egg - the latter means catalytic converter, gas smell probably flooded or not firing on one or more cylinders, need more details. Also, if the light is flashing it's warning of catalytic damage - raw fuel hitting the cat, smell could be heat from cat trying to burn off raw fuel,it will glow red hot.

My 1997 lesabre runs fine until Im at a stop then it idles ruff it is less sever when in park but bad when im stop using the brakes


Could be the Idle Air Control if so equipped. The smoother idle is because when in neutral or park, there is no drag on the engine from the transmission.

Only runs ruff during park and idle.


Your EGR valve shouldn't open up during idle or the engine will run rough and may even stall. Remove it and clean the plunger and port with a wire brush and some carb cleaner. Test the diaphragm with a vacuum pump. If it doesn't work after cleaning, or the diaphragm is bad, buy a new EGR valve.
