Well the black smoke indicates a rich air fuel ratio, when the check engine light is on take it to autozone and ask them to pull the code, they will do it for free and tell you the malfunction the ecu is picking up then just replace that part or get back to me and i will help you with what ever code your car is pulling. take care

Why are my glow plug light is flashing all the time and on first start in morn it coughs and splutters and smokes bad from exhaust wat is wrong had coolant temp sensor changed today please help im a female...


I think you are referring to a different indicator light. A glow plug is a Diesel engine part and I do not think an American version has a Diesel. There is a "check engine light" which is an indicator of trouble and will display as you described.

Go to a Advance , Autozone, or Oreilys autoparts store. You can ask for a free scan to diagnose your problems. The coolant sensor can relate to a cold start problem. Some models use 2 temperature sensors. One operates the dash gauge and the other operates engine controls.

You will need to know if you replaced the sensor to the dash gauge instead of the engine control sensor. Both use heat to set engine controls.

Engine light came on wit lack of power spluttering and wgite smoke from exhaust


Dear Sir,
As you said engine light is on and misfire with white smoke, it clearly symptom of poor ignition spark may cause of any wire got disconnected or spark plug faulty.
white smoke comes only in case no spark at spark plug and un burn fuel throwing from silencer. check wire and spark plug if any issue let me know. thanks.

It appears you have possibly a bad MAF sensor. It's in the intake duct. If its dirty, wash it off with CRC electrical cleaner. Do not touch, rub or brusj. dries quickly. See if this helps. Good Luck, Ned

My cougar does the same, it starts and then about 1 minute later (or so) the check engine light comes on and the car idles really high, with black smoke out the exhaust. It stays in second gear i think and it will not shift out of it. Max speed is 40 mph with the rpms screaming, it will go off after a long time but this is agrivating. I have a 94 mercury cougar xr7 3.8 ltr Any help please?

Glow plug light flashes on97 tdi sharan


on some diesel engines the glow plugs will cycle after the engine is started. it does sound like your glow plugs are not all working that would cause the hard start and excessive smoke when it does start.
