White smoke is water vapor and in this cold climate it is normal. Strong gas smell is not normal although you may smell some while engine is warming up. Bad cat converter can produce smells, but usually more like rotten eggs. If engine is running rough and seems rich, check coolant temp sensor. Bad converter can cause stalling too. Otherwise, idle speed is controlled by idle air contol motor which can get dirty and stick. Any codes set?
Bad coolant temp sensor making ECU think engine is still cold, thus running rich, as if choke is on. There are two temp sensors, one for dash gauge (one wire) and one for the ECU (two wires). You can remove it and test with voltmeter by placing unit in hot or cold water to compare readings.
from where, end of tail pipe or ?????????????
tail smoke has 2 types,. oil and steam.
1: steam smells sweet(glycol) and goes away fast.
2: oil smoke, smells like burnt oil and takes a vary long time to go byebye.
or is normal.
all cars burning gasoline make water (H2O) as a byproduct, of combustion the seems to go away on a hot day.
but really does not, it just seems to.
on a cold day all cars make steam
if yours is and your neighbors car dont at the SAME time (out door temps same) then your steam is wrong. a bad sign of bad head gasket or far far worse , a cracked head.
did you do the pre fall service, and check antifreeze protection levels.
a $2 tool that save cracked engine blocks.
Take the air cleaner off and open the throttle (have someone hold the gas pedal to the floor) and look down into the intake manifold, if you see gasoline, the Fuel Pressure Regulator may be leaking sometimes there are plastic fuel lines inside that can leak also. When either of these leak, the engine should run REAL BAD/RICH. Black smoke coming from tail pipe.
If the smoke comming from the tail pipe is black your running rich. If thats the case the entire fuel system has to be ckecked out. Injectors could be leaking, a bad pressure regulator,stuck return line ,a coolant temp sensor could be telling the ECU that the engines cold give her more gas. I don't recommend doing fuel service unless your qualified to do so for the obvious reasons.
If the smoke coming out of the tail is grayish you have a bad head gasket. If the smoke coming out of the tail is blue you have engine oil getting into the combustion chamber. keep me posted
first check fuel pressure regulator for a ruptured diaphram,by removing the vacuum line and look,smell for gas,if there is replace reg.if ok check fuel pressure,may be to high,.have you checked for engine codes?you may have a mass air flow meter problem,coolant temp. sensor out of range,leaking fuel inj.need to take the car to a repair shop.
The Symptoms tell me it is a head gasket. A leaky or bad head gasket would cause all of the problems that you mentioned.
Burning water causes White Smoke, Burning Oil causes Black Smoke. The oil and water are mixing with the gas in the cylinders and causing it to run bad. Pull out the dipstick and look at the oil on it. Does it look like good oil? Or does it look watery and or foamy or grey colored. Open up the radiator and look inside, do you see oil?
This seems almost text book to me... I would have someone local to you to have a look at it to be sure.
