It is possible the belt is slipping causing tbe smoke. Alternator is not charging. It may be locked from bearing going bad so it doesnt turn. Hope this helps.

Sounds like the alternator bearing is going bad and it is not turning freely when the serpentine belt trys to turn it. because of this the belt is slipping on the alternator pulley and causing it to burn. thats why you are getting the smoke in the cab of the car. the smoke should have a burning rubber odor. if this is the problem. you need to replace the alternator.

Sounds like you have a main lead from the positive earthing on the body or engine somewhere check the lead from the battery to the alternator or starter then to altenator

SOURCE: 2000 taurus. rough idle when stopped check engine

This sounds like a MAP sensor. Have it scanned for the codes to make sure. Your mechanic can do this orany Ford Dealer for 75 - 100.00. I'm 98% sure this is a MAP sensor problem. Any questions please feel free to ask. Chris J.C. Towing

SOURCE: engine light is blinking and the car runs rough,not enough power.

You shouldn't have taken the car back,nor should the shop given you the vehicle,if you were willing to have it properly repaired.
The MIL Light is an indication of an issue or two and you said it runs rough and has no power. What more does a shop need. Repair it.

Is the Fuel Filter fairly new
Did they Clean the MAF Sensor,and make sure your air filter cover is on correctly,and you have no vacuum leaks.
They can look at all sensor data and resolve this ,if they wanted to.

Car running rough along with stains of what appears to be oil on both sides of car


Having worked on several cavaliers this year, I have found a tune up took care of the rough running condition, and all of them had valve cover oil leaks.
So consider replacing the valve cover gaskets and the spark plugs.

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.

2003 ford expedition.. we have already replaced the iac but it is still idling rough when you come to a complete stop.. it is almost like the car is gonna cut off but it doesnt.. what could be causing...


Is the check engine light on? If so have you checked for codes? Do you have a P0171 and P0174 codes?

If so, and your symptom supports this, you may have a vacuum leak. This could be anything from bad plenum gaskets to a rotted out rubber elbow. Normally I would suggest using carb spray to find the vacuum leak but carb spray is flammable and since the coils are on the top side of the engine you need to be really careful not to get it near the coils as the engine could catch fire.

What I would suggest is having the engine smoke tested. This uses a machine that pressurizes the intake system with a low pressure smoke. the smoke will come out of wherever the leak is.

Started my 2002 ford taurus this morning just fine. Let it run for about 15 minutes before leaving fo work. When I came out my car was idling very rough and white smoke would come out the back then...


Have it checked at your local garage. White smoke from the exhaust system.....normally means a cracked cylinder head gasket. I would check the oil dipstick to ensure that there is no coolant in the oil pan. Coolant in the oil pan could mean a cracked cylinder head......a more costly repair.

Is the alternator for 2003 sante fe located on the top or bottom of engine.


It's not on top or bottom... it's on the 'SIDE' of the engine.... and depending on which engine you have, it could be on the left SIDE or the right SIDE. On the four (4) cylinder engine, it's on the Right Side (firewall side), and on the other two V6 engines, it's on the Left Side (radiator side).

My 2003 Ford Taurus idles very rough and will die at stops if my a/c or heat is on. Don' know why?


When was your last tune up? Change spark plugs, Check fuel pressure at the fuel rail 30psi.
How many miles on car? Have alternator checked out. If you need and alternator your looking at $900 and up its not easy to change. You have to move power steering pump out of the way to unbolt the top bolt. Then you have to take the right side tire off pop the balljoints, then pull the axle to unbolt the other two bolts and pull alternator out at the bottom where the axle was.
