You may want to check your oxygen sensor and vacuum hoses. An OBD can help you identify the exact cause. Most auto store and garage should have one.

2003 ford taurus emission system light is on


By "Emission Light", I assume you mean the "Check Engine" or "Malfunction Indicator Light (MIL)? Well, to get a clue to what you are asking, please review the following article:

2004 ford escape engine emission light on lunges while idleing


I have found this to be a common problem on 2001-2006 V6 Ford Escapes. In 99% of these cases the problem is the Catalytic Converter. The V6 has three in-total, one per exhaust manifold, and one after the Y connection. This third catalytic converter is the one that always gets clogged. Another clue to it's failure is a loss of power and a increase in fuel consumption. The later 2006-2008 have a redesigned exhaust system. Hope that helps.

In my 2005 Ford Escape, my check emission system light constantly comes on, but then will shut off randomly. What causes this problem, or could this just be some sort of electrical malfunction?


It is a malfuntion alright
Anytime you get any light on the dash,you got problems
These lights have been on vehicles for 30 years,still there are thousands of people on this site along, who have no clue,no owners manual,and on and on.
Check for the code and have it repaired,won't go away
Part of the Govt's attempt ,for the last 50 years, to cut down on Exhaust Emissions,but people don't care.

What does po440 on a 2003 saturn vue mean with a service engine soon light on


That is a problem in the evaporative emission control system.
Could be anything causing it
Clogged filter in the charcoal canister
A leak in one of the vacuum lines
The purge valve not working,,,etc.
The best thing is to take it and have it checked out, they might have to do a smoke test to find the problem.
All they do is inject smoke into the system, if there is a leak the smoke will come out of it. All it takes is a pin hole in these emission systems to screw it all up.

Service emission warning


theres a problem with the emission system,maybe a bad fuel cap or a leak in the system, you would need to have the computer scanned for codes, these codes will give you an idea of whats not working, auto zone car parts will scan your codes for free, start with that.

code 452 is EVAP emission control system pressure sensor low
motor is surging?
EGR may be blocked

2005 xA won't start


there's a possibility that the battery is run down. If it's the original battery, chances are you need to replace it. I'd have the alternator checked as well, however the most likely problem is a worn out battery. It's not uncommon for batteries that have been maintaining their charge through the warmer months to go bad once a cold weather comes through. As for the stinky exhaust, in your attempts to start the engine with a run down battery, the engine probably loaded up with fuel, thereby causing it to run rough and stink till excess fuel was expelled from the cylinders. Hope this helps.
