You got it . it is more than likely you have vacuum leak . to chek use a propane torch and while idling intoduce propane at possible area(intake gasket, egr valve , brake booster etc) if idle speeds up and smooth fix it.

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

Where is Idle control valve located and how do you know if it's bad? My 1994 Toyota pick is idleing ruff and skips a little while running down the road. I've changed the plugs and wires also had the head...


Idle air control valve only controls air into the engine while idling. If your vehicle is running rough and skips, its misfiring. Make sure that the new plugs are properly gapped and timing is set right on the distributor side, intake hose isnt leaking. Re-inspect the sparkplugs for fouling (black, burnt, brown etc). if ok, have the computer scanned for the error at autozone (free). Post the code online...hopefully this helpd
