Flashing emissions light
\015 The emissions light is on pretty much all of the time and recently when I drive over 45 mph it starts flashing. The car was recently inspected and passed, but the engine is loud, especially when first starting up. After driving for a while it gets better, but the engine doesn't run smoothly on a regular basis. I am not even sure if that is related to the emissions light, but it gets worse when the light is flashing, so it might be.\015

CHECK ENGINE LIGHT WONT LIGHT.MUST LIGHT WITH KEY ON TO PASS EMISSIONS .I ALREADY REPLACED THE BULB WHICH WAS BAD'CHECKED CIRCUIT BOARD OK. ALSO TURN SIGNALS WORK NORMAL BUT WHEN YOU PUT THE 4WAY FLASHERS ON THE LIGHTS ALL FLASH NORMALY EXCEPT THE INSIDE INDICATORS IT FLASHES THE HIGH BEAM IND. INSTEAD I REPLACED THE FLASHER UNIT AND THE TURN SIGNAL MULTIFUNCTION SWITCH.

Check engine light is on, service emissions system flashes on console, oil light will flash and car cuts off at random, sometimes car will backfire and cut off. Lots of exhaust when trying to accelerate or sometimes when starting car. Ran a computer diagnostic check for error codes and came up with: PC0113, PC1111, PC1153, IP2711, AC1347, RS0038 and RF2560. Can you tell me what these codes mean and where I should start with repairs?

Hi, I have a 2001 Chrysler T&C. Check engine light is on for #2 & #5 misfires and cam sensor codes. Small emissions leak. This began after I had the transmission rebuilt. Replaced plugs, wires, fuel filter & coil:but light came back on. Engine light flashes when accellerating but drives fin. Only felt the misfires once when van didn't accellerate immediatley like it usually does. Could it be carbon build up? Should the mechanic replace the cam sensor? Could the fly wheel have cracked when trans.

I have a 2003 Dodge Ram Hemi. An amber light in the upper left dash and a flashing red light in the lower right is displays periodically. When this happens the engine runs very rough and wants to cut out etc...Is this an emissions problem? The truck is still under warranty. Less than 70,000 miles and less than 7 years. I also have an oil leak coming from just inside the left front aprox. 12 to 18 inches over. The fluid is red in color. Is this the 4wd gearbox oil or power stirring?
Use the warranty, if you get someone to poke around it could void the warranty.\015\012 Red fluid is normally transmission fluid, sometimes power steering. Is the fluid oily or watery, some brands of antifreeze are red.\015\012 A flashin ... 2003 Dodge Ram Maxi

I have a Peugeot 407 SW 2.0 HDI I have recently had the particulate fluid topped up and engine management reset. The car is running well but a warning light has come on--not flashing, saying 'emission control system fault'. The car has done about 110000miles and is early 2005. How critical is this and what do you think I should do about it? PS the drop down menu doesn't include the 407 which is why I have put 405 All suggestions welcome, Thanks, Ian Brown.
You need to have an OBII scan done (fault scan). Scan will identify what sensor triggered light. It may or may not be "critical" but it's worth investigating before it gets worse and causes more damage. ... Peugeot 405
