When you have the car in gear there is a load on the engine. If you are for some reason not getting good fuel then its trying to compensate by kicking the idle up. When you are just in park there is no load so its not struggling. Regularly using a fuel system cleaner will help with rough idle, as well as hesitation. Also it might be good to check the fuel pressure regulator.

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

My 2004 ford expedition idles rough like its going to cut off The idling jumps up and down in park or drive only when stopped Service engine light cuts off and on periodically what could be happening


run a teat. Remove the vacuum line from the brake booster and plug off. Start engine and see if it idles normally. . Put your foot on the brake pedal and apply the brakes . If the idle is still normal replace the brake booster as there is an air leak in the diaphram.. The service light is probably recording misfiring and air fuel mixture problems.. run fault codes any way just to check it out .

Here are the most common causes of idle surge, rough idle esp when cold, other symptoms include stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue 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

My 2001 Mitsubishi Galant 4 cylinder is idling high in park and when put in drive it starts idling low, runs rough, and acts like it wants to die at stop lights


This is a typical vacuum leak. Check all the hoses. If none are sucking air then use WD40 and spray around the intake manifold. If the engine runs better or changes how it runs then look at replacing the intake manifold gasket.

I have a 1991 Buick Park Avenue. Runs rough in


Here are the common cause of surges, cold stalls, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours.
To correct this problem I want you to get a can of intake cleaner (ABOUT $5.00) from any local auto parts store like NAPA or Carquest, do not use carburetor spray, intake cleaner only or u will damage the Teflon coating inside the throttle valve and air bypass valve, 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.

Car idles rough in park also runs rough in overdrive


Sometimes a rough idle like that is a fuel filter. As you've already done the plugs and wires the fuel filter would be my next bet.
