Before you throw down a wad of cash on repairing the cat converter, get the Fuel Pressure Regulator Sensor changed.

I Have a Ford Taurus 2006 when you start this car it dies and I noticed blueish smoke comes from the exhaust and the fuse blows out


Blue smoke on startup is a sign of worn valve stem seals. But worn seals wouldn't cause it to die after starting. Check the engine coolant temp sensor. Take a look at these known issues for Taurus

CAR FLOODED, REPLACED MAS, SPARK PLUGS, FUEL FILTER, FLUIDS, AND FUEL PUMP DRIVEER MODULE...CAR NOW STARTS BUT VERY ROUGH IDLE AND DIES OUT IF YOU DONT KEEP FOOT ON THE GAS


remove and clean the idle sensor valve. pull out and clean the PCV valve (on top of the valve cover).blow out (from the inside) the air filter. do not apply gas until after your vehicle starts.

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

2003 taurus runs rough and flashing engine light


The big autoparts stores like Autozone will test your car for free with their scanners. The clerk should be able to tell you some of the possible problems. Get a problem Code from them.

Sometimes the results point to a single part or several parts needing further troubleshooting.

I have 2003 ford focus 2.0 SOHC SPI with a bad missfire


Yup, been there, done that. Found it was a bad injector. Replaced that one injector the test showed and runs great now. Check engine light should be on though because of this problem. The test will show you which cylinder is misfiring and that is the injector you change. My test showed #5 cylinder. The last # in the code read.

We just purchased a 2002 Ford Escort. Tonight, when starting the car, it ran very rough and then died. We started it again and it ran fine after that. It has happened twice and it has only happened when...


Could be a idle air problem. The injector could be leaking when you shut it off ..Try some injector cleaner see if it gets better..The idle air shouldnt run rough just idle real low or sometimes it will get stuck and idle high....Are you losing any antifreeze..If you are the 2.0 SOHC engine bad about leaking antifreeze into the cylinder and makes the engine run rough until it burns it out..See if you can see the smoke coming out when it happens..White smoke indicates antifreeze,,Black smoke indicates fuel..
